PROBLEM TO BE SOLVED: To prevent recess marks from being generated on the surface of a weather strip in which a core material is embedded. SOLUTION: In the core material 16 embedded in the weather strip 13, a plurality of the core material pieces 22 are linked in a predetermined spacing and the separating spaces 24 are formed between the pieces 22. The packing polymer material P2 is filled in each separating space 24 in a thickness nearly the same as that of the core material pieces 22 and the entire surface of the core material 16 is covered with the packing polymer material P2. By this, in forming the weather strip 13, the thicknesses of the polymer material P1 for forming the trim are made almost identical between the part where the material P1 covers the core material pieces 22 and the part where it covers the separating spaces 24 filled with the packing polymer material P2, and thus the difference of the molding shrinkage amounts of the thickness direction of the trim molding polymer material P1 can be mostly eliminated.
