Abstract: To provide a decorative member that has a small transmission loss of a millimeter wave and excellent metallic luster. The decorative member includes a base material made of a synthetic resin and a film body that made of an agglomeration of inorganic fine particles having at least a metal surface. An attenuation rate when a millimeter wave having a frequency of 18 to 300 GHz transmits is 0.001 to 2 dB, and an L* value (brightness) is 45 to 95.

Abstract: A battery device is provided with cooling bodies for contacting the outer surfaces of a plurality of battery cells arranged inside a battery case, and spacers provided adjacent to the cooling bodies. The cooling bodies absorb or are impregnated with a cooling fluid inside the battery case. Cooling medium vapor flow channels in which cooling medium vapor circulates are formed on the surfaces of the spacers facing the cooling bodies, the cooling medium vapor being generated by the evaporation of the cooling fluid of the cooling bodies.

Abstract: An injection molding method includes a holding step, a cavity forming step, a first injection step, a compression molding step, and a second injection step. In the holding step, a skin layer is held under tension by tension pins. In the cavity forming step, a male mold and a female mold are disposed in facing relation to each other, forming a molding cavity therebetween with a gap between the male and female molds being grater than the thickness of a door trim (body of synthetic resin) by a predetermined distance. In the first injection step, a molten synthetic resin is injected from a first injection gate into the molding cavity. In the compression molding step, the male mold and the female mold are displaced toward each other by the predetermined distance, compression-molding an upper portion (first portion) of the door trim of the molten synthetic resin.
