PURPOSE: To provide a three-dimensional hollow molding which prevents an opposite part to the resin injection part of a core which is inserted and mounted in the cavity of a die from becoming deformed by a pressure originating from a melt injection resin at the time of coated molding. CONSTITUTION: This three-dimensional hollow molding consists of a resin core 20 with a hollow part 21, and a resin coated member 30 which is formed by injecting a molten resin from a resin injection part 41 provided in a die into a space 44 formed by the core 20 mounted in the cavity of the die and the die face 43 of the cavity, and covers at least, a part of the outer face of the core. In addition, the opposite part 23 of the core to the resin injection part 41 is thick. |
