A general-purpose LED that has small discoloration due to thermal deterioration and excellent heat-resistant discoloration, has a long life, is relatively inexpensive, and has excellent material storage stability, handling properties, and workability. A resin composition for a reflector, an LED reflector using the resin composition, and an LED lighting apparatus are provided. A dry-type unsaturated polyester resin composition comprising at least an unsaturated polyester resin, a polymerization initiator, an inorganic filler, a white pigment, a release agent, and a reinforcing material, wherein the unsaturated polyester resin is the entire composition. The total amount of the inorganic filler and the white pigment is within the range of 44 to 74% by mass with respect to the total amount of the composition, The ratio of the white pigment to the total amount of the white pigment is 30% by mass or more, and the unsaturated polyester resin is a mixture of an unsaturated alkyd resin and a crosslinking agent.
