Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a mold and a molding method which are capable of forming a corner part free from a crease by conducting hot setting of an extruded article, and a weather strip molded thereby. SOLUTION: The whole of the weather strip 1 for an automobile having a hollow seal part 2 fitted to a fitting base part 3 is formed by extrusion. The extruded article E thus formed is set in a state wherein a part thereof is curved, and the corner part C is formed by the hot setting. In this mold, a pressing-in split part 16 to be pressed into the root part 2a of the hollow seal part 2 positioned inside the corner part C is shaped in an almost rectangular section, while the wall thickness T of the split part 16 is set to be large enough to prevent formation of the crease W in the hollow seal part 2, so that a region 2c continuous to the root part 2a of the hollow seal part 2 be raised.
