PROBLEM TO BE SOLVED: To provide a resin composition that prevents the occurrence of a crack in even a molded article that is molded with the resin composition comprising a large amount of an inorganic filler comprising a white pigment relative to a polyolefin resin, shows excellent heat resistance and has a white color tone, and a resin frame for a reflector, a reflector, a lead frame with a reflector and a semiconductor light-emitting device obtained by molding the resin composition.SOLUTION: A resin composition comprises a polyolefin resin and an inorganic filler comprising a white pigment, where the polyolefin resin has a weight average molecular weight of 220,000-800,000, and the white pigment is contained at the rate of more than 200 pts. mass and 500 pts. mass or less relative to the polyolefin resin 100 pts. mass.SELECTED DRAWING: Figure 1 |
