The layered panel in accordance with claim 1, wherein the first link section between the first depression contour and the second depression contour is bent, anda second link section between the second depression contour and the bottom surface is bent. 3. The layered panel in accordance with claim 1 wherein the intermediate layer includes a first portion and a second portion,the hinge is defined at least by the first portion of the intermediate layer,the depression contour is provided in the first portion of the intermediate layer, the first portion of the intermediate layer is depressed in the direction from the rear wall side to the front wall side, andthe intermediate layer includes at least one groove defined in the second portion of the intermediate layer that is depressed in the direction from the front wall side to the rear wall side, and the at least one groove is buried by a resin that defines a portion of the front wall. 4. The layered panel in accordance with claim 3, wherein the groove is provided adjacent to a standing wall of the depression contour that connects a starting point of the depression contour and an outer edge of the bottom surface. 5. The layered panel in accordance with claim 3, wherein the first portion of the intermediate layer that defines the hinge is interposed between the front wall and the rear wall. 6. The layered panel in accordance with claim 1 wherein the hinge is defined at least by a first portion of the intermediate layer,a holding section is defined in at least a second portion of the intermediate layer, and the holding section is a deformed portion of the second portion of the intermediate layer that holds a reinforcement member. 7. The layered panel in accordance with claim 6, wherein the holding section is a click section disposed at a notch in the second portion of the intermediate layer, andthe reinforcement member is held by the click section. 8. The layered panel in accordance with claim 7, wherein the first portion of the intermediate layer that defines the hinge is interposed between the front wall and the rear wall. 9. The layered panel in accordance with claim 6, wherein the reinforcement member is sandwiched between the holding section of the intermediate layer and one of the front wall and the rear wall. 10. The layered panel in accordance with claim 3, wherein the at least one groove of the intermediate layer includes two grooves, defined across the depression contour in the second portion of the intermediate layer, that are depressed in the direction from the front wall side to the rear wall side, andthe grooves are buried by a resin the defines a portion of the front wall. 11. The layered panel in accordance with claim 1, wherein the intermediate layer includes a foaming material, and a portion of the foaming material provided at the flat bottom surface has an expansion ratio of 2.0 or less. 12. The layered panel in accordance with claim 11, wherein another portion of the foaming material of the intermediate layer provided at the first and second sections has an expansion ratio of 2.5 to 5.0.
