PROBLEM TO BE SOLVED: To improve efficiency in core removal work by easily removing out the core while making an opening area formed in a hollow part of a die molding part for core removal as small as possible. SOLUTION: In the weather strip comprising a welt part 6 and a hollow-like seal lip 7, the die molding part 8b is formed so as to be continued to a general part 8a. An end surface in a longitudinal direction of the die molding part 8b is opened as a core removal hole 14. On the seal lip 7 of the die molding part 8b, a bellows-like expansion/contraction easiness part 15 folded/bent in an approximately U shape such that an inner peripheral surface side becomes a projection shape and an outer peripheral surface side becomes a recession shape and one crest part or bottom part of the so-called bellows shape are cut out is formed so as to be continued to the core removal hole 14.
