PURPOSE: To firmly stick a base material to a surface layer and efficiently produce a weather strip without necessity of a lot of production processes by interposing adhesive component composed of specified components between a base material composed of ethylene-propylene rubber, and surface urethane layer.
CONSTITUTION: In a weather strip for an automobile comprising urethane layer formed on the surface of the base material composed of ethylene-propylene rubber, an adhesive component composed of epoxy radical containing acrylic elastomer, ethylene-α-olefinic copolymer, organic peroxide, and primary amine or imidazole compound and having weight ratio of (epoxy radical containing acrylic elastomer)/(ethylene-α-olefinic copolymer) 60/40-40/60 is interbased between a base material and an urethane layer. Calcium oxide can be contained in peroxide and primary amine or imidazole compound.
