PURPOSE: To provide a three dimensional hollow molding capable of preventing a core fitted by insertion into a cavity of a mold from being deformed by pressure caused by melt injected resin in molding a jacket.
CONSTITUTION: A three dimensional hollow molding is molded by injecting a molten resin 46 from a resin injection part 41 provided on a mold into a space 44 formed by a resin-made core 20 having a hollow part 21 and, a mold surface 43A of the core 20 fitted in a cavity 43 of the mold 40 and the cavity. The three dimensional hollow molded product is composed of a resin-made jacket component 30 covering at least a part of an outer surface of the core 2, and a part opposed to the resin injection part 41 is composed of only the jacket component 30.
