A weather strip comprises an extruded portion and a molded portion which is integrally connected to a longitudinal end portion of the extruded portion. The extruded portion includes a sealing portion formed by extrusion molding from a sponge rubber, soft thermoplastic elastomer or sponge thermoplastic elastomer, and an attachment portion having a separable core member embedded therein and formed by co-extrusion molding from a solid rubber, low foamed rubber or thermoplastic elastomer. The molded portion comprises a sealing portion formed of a soft thermoplastic elastomer or spongy thermoplastic elastomer, and an attachment portion formed of a semi-rigid resin.

1. A weather strip comprising: an extruded portion having a longitudinal end portion; a molded portion having a longitudinal end portion which is integrally connected to the end portion of said extruded portion; wherein said extruded portion comprises a hallow sealing portion, formed by extrusion molding from a material selected from the group consisting of sponge rubber, thermoplastic elastomer and sponge thermoplastic elastomer, and an attachment portion, having a core member embedded therein, and formed by co-extrusion molding from a material selected from the group consisting of solid rubber, foamed rubber and thermoplastic elastomer; wherein said molded portion comprises a hollow sealing portion formed of a material selected from the group consisting of thermoplastic elastomer and sponge thermoplastic elastomer and an attachment portion formed of a semi-rigid resin; wherein said thermoplastic elastomer for said sealing portion of said molded portion has a Shore A type hardness of 30° to 60°; and wherein said semi-rigid resin for said attachment portion of said molded, portion has a Shore D type hardness of 30° to 65°. 2. A weather strip according to claim 1, wherein said extruded portion further comprises a decorative cover formed of a material selected from the group consisting of resin, thermoplastic elastomer, foamed resin, and foamed thermoplastic elastomer; and wherein said decorative cover is formed on an outer surface of said attachment portion of said extruded portion and extends as far as a terminal side edge of said extruded portion. 3. A weather strip according to claim 2, wherein said decorative cover and said attachment portion of said molded portion have an identical color. 4. A weather strip according to claim 1, wherein said extruded portion further comprises a covering lip portion, which is formed integrally to said attachment portion of said extruded portion and protrudes therefrom. 5. A weather strip according to claim 4, wherein said extruded portion further comprises a decorative cover formed of a material selected from the group consisting of resin, thermoplastic elastomer, foamed resin, and foamed thermoplastic elastomer, and wherein said decorative cover is formed on outer surfaces of said attachment portion and said covering lip portion of said extruded portion and extends as far as a terminal side edge of said extruded portion. 6. A weather strip according to claim 5, wherein said decorative cover and said attachment portion of said molded portion have an identical color. 7. A weather strip according to claim 1, wherein said molded portion has a curved shape.
