摘要： The invention is to provide a resin molded article for electric part having excellent heat resistance, mechanical characteristics, electric characteristics, dimensional stability, flame retardancy and molding properties and capable of being subjected to usual injection molding and a production process of the same. The resin molded article for electric part is one resulting from molding and solidifying a resin composition containing a thermoplastic polymer, a crosslinking agent made of a polyfunctional monomer or oligomer containing an unsaturated group in ends of the major skeleton, an inorganic filler, and a reinforcing fiber and then crosslinking said thermoplastic polymer by radiations. The crosslinking agent is kneaded with the thermoplastic polymer and the reinforcing fiber and the like after an adsorbing step for adsorbing onto the inorganic filler in advance, and after injection molding, irradiation with radiations is performed.
