This unsaturated polyester resin composition contains (a) an unsaturated polyester resin, (b) a metal soap, (c) a carboxylic acid, (d) an inorganic filler, (e) a shrinkage reducing agent, (f) a fiber reinforcing material and (g) a curing agent. In this unsaturated polyester resin composition, 1-3 parts by mass of the component (b), 5-15 parts by mass of the component (c), 350-550 parts by mass of the component (d), 10-30 parts by mass of the component (e) and 70-120 parts by mass of the component (f) are contained per 100 parts by mass of the component (a). An unsaturated polyester resin composition having the above-described composition is capable of providing a molded body which exhibits excellent coatability of an undercoating agent, mold releasability and fogging properties without performing a removal process of a mold release agent, while having excellent dimensional accuracy and mechanical characteristics. |
