Abstract
A resin composition including an olefin resin, an alkenyl-containing alkoxy silane compound, and at least one inorganic filler selected from the group consisting of titanium oxide, alumina, talc, clay, aluminum, aluminum hydroxide, mica, iron oxide, graphite, carbon black, calcium carbonate, zinc sulfide, zinc oxide, barium sulfate, and potassium titanate; a reflector using the resin composition; a reflector-bearing lead frame; and a semiconductor light-emitting device. Accordingly, provided by the present invention are: a resin composition capable of expressing an excellent heat resistance (especially heat distortion resistance) even when it is made to a formed body; a reflector using the resin composition; a reflector-bearing lead frame; and a semiconductor light-emitting device.
