Abstract

A low-specific-gravity unsaturated polyester resin composition for lamp reflector that exhibits low specific gravity of molding, being free from variation and excels in molding properties, such as surface smoothness, thermal stability, mechanical strength, rigidity, dimensional precision and moldability; and a molding thereof. There is provided a low-specific-gravity unsaturated polyester resin composition for lamp reflector, comprising an unsaturated polyester resin and a crosslinking agent and further, per 100 parts by mass thereof, 40 to 210 parts by mass of inorganic filler, such as calcium carbonate, of 0.5 to 15 μm average particle diameter and 30 to 160 parts by mass of hollow filler, such as glass balloon, of 2100x10<SP>4</SP> N/m<SP>2</SP> or greater pressure withstanding strength and 0.3 to 0.7 true specific gravity, the loading mass ratio of inorganic filler : hollow filler being in the range of 2:8 to 8:2.
