PROBLEM TO BE SOLVED: To provide a method for manufacturing an inmold molded foam which can mold a foam in a mold under a low temperature molding condition by applying an approximately equal heating pressure even when polypropylene preliminary foamed particles have different characteristics, and the inmold molded foam. SOLUTION: In the method for manufacturing the foam in the mold in which two or more types of the polypropylene preliminary foamed particles having different characteristics are approximately sectionally exist, at least one type of the polypropylene preliminary foamed particles composing one section is a base resin of a polypropylene resin composition including 100 pts.wt. of a polypropylene resin, and not less than 1 pt.wt. and not greater than 8 pts.wt. of an aliphatic petroleum resin and/or an alicyclic petroleum resin.
