The panel member molded from a fiber reinforced plastic material includes the waved plate section. In the waved plate section, lateral wall portions are connected to upright wall portions through bent portions. Each lateral wall portion includes a general portion extending along the wavelength direction of the waved plate section. A plate thickness of the general portions of the lateral wall portions is set thinner than a plate thickness of the upright wall portions. The general portion at least does not include bubbles with a larger diameter than reinforcing fibers. An array direction of the reinforcing fibers disposed in the general portion of the lateral wall portion is set in a direction running along the wavelength direction of the waved plate section.

1. A panel member, comprising: first wall portions that form undulations of a waved plate section molded from a fiber reinforced plastic material; andsecond wall portions that configure upper and lower end portions in a wave height direction of the waved plate section, and that are connected to the first wall portions by bent portions, wherein:the second wall portions each include a general portion extending along a wavelength direction of the waved plate section, and the general portions are set with a thinner plate thickness than the first wall portions;an array direction of reinforcing fibers disposed in the general portions is set in a direction running along the wavelength direction of the waved plate section; andextension portions extend out from the bent portions at an opposite side to a first wall portion side, and the extension portions are integrally formed with the bent portions. 2. A press mold, comprising: a lower mold that includes a first molding face employed to press-mold the panel member of claim 1; andan upper mold that is disposed facing an upper side of the lower mold, that includes a second molding face employed to press-mold the panel member, and in which a region of the second molding face that molds the general portions of the second wall portions is set with a narrower gap to the first molding face than a region of the second molding face that molds the first wall portions. 3. A manufacturing method of a panel member employing the press mold of claim 2, the manufacturing method comprising: a first process in which, in a state in which a fiber reinforced plastic material in sheet form is disposed on the lower mold, the second molding face of the upper mold is brought into relatively close contact with the first molding face of the lower mold, and the fiber reinforced plastic material is formed in a waved plate shape; anda second process in which, after the first process, the second molding face of the upper mold is brought into relatively even closer contact with the first molding face of the lower mold, and a region that becomes the general portions of the second wall portions is compressed in a general portion plate thickness direction. 4. The panel member of claim 1, wherein the general portion at least does not include bubbles that have a larger diameter than the reinforcing fibers. 5. The panel member of claim 1, wherein: the bent portions are formed in a curved shape and are set with the same plate thickness as the first wall portions; andgradual change portions with gradually decreasing plate thickness on progression away from the bent portions are formed at an end portion at a bent portion side of the second wall portions. 6. The panel member of claim 1, wherein: the bent portions are formed in a curved shape and are set with the same plate thickness as the second wall portions; andgradual change portions with gradually increasing plate thickness on progression away from the bent portions are formed at an end portion at a bent portion side of the first wall portions. 7. A panel member, comprising: first wall portions that form undulations of a waved plate section molded from a fiber reinforced plastic material; andsecond wall portions that configure upper and lower end portions in a wave height direction of the waved plate section, and that are connected to the first wall portions by bent portions, wherein:the second wall portions each include a general portion extending along a wavelength direction of the waved plate section, and the general portions are set with a thinner plate thickness than the first wall portions;the first wall portions are formed perpendicularly to the second wall portions;an array direction of reinforcing fibers disposed in the general portions is set in a direction running along the wavelength direction of the waved plate section; andextension portions extend out from the bent portions at an opposite side to a first wall portion side, and the extension portions are integrally formed with the bent portions. 8. A press mold, comprising: a lower mold that includes a first molding face employed to press-mold the panel member of claim 7; andan upper mold that is disposed facing an upper side of the lower mold, that includes a second molding face employed to press-mold the panel member, and in which a region of the second molding face that molds the general portions of the second wall portions is set with a narrower gap to the first molding face than a region of the second molding face that molds the first wall portions. 9. A manufacturing method of a panel member employing the press mold of claim 8, the manufacturing method comprising: a first process in which, in a state in which a fiber reinforced plastic material in sheet form is disposed on the lower mold, the second molding face of the upper mold is brought into relatively close contact with the first molding face of the lower mold, and the fiber reinforced plastic material is formed in a waved plate shape; anda second process in which, after the first process, the second molding face of the upper mold is brought into relatively even closer contact with the first molding face of the lower mold, and a region that becomes the general portions of the second wall portions is compressed in a general portion plate thickness direction. 10. The panel member of claim 7, wherein the general portion at least does not include bubbles that have a larger diameter than the reinforcing fibers. 11. The panel member of claim 7, wherein: the bent portions are formed in a curved shape and are set with the same plate thickness as the first wall portions; andgradual change portions with gradually decreasing plate thickness on progression away from the bent portions are formed at an end portion at a bent portion side of the second wall portions. 12. The panel member of claim 7, wherein: the bent portions are formed in a curved shape and are set with the same plate thickness as the second wall portions; andgradual change portions with gradually increasing plate thickness on progression away from the bent portions are formed at an end portion at a bent portion side of the first wall portions.
