Abstract

An unsaturated polyester resin composition includes: a resin component comprising an unsaturated polyester, a polymerizable monomer, and a low profile agent; aluminum hydroxide; and a fire retardant. The unsaturated polyester is a polymerized product of polybasic acid and polyhydric alcohol. The polybasic acid has an ethylenic unsaturated double bond at a predetermined ratio. The polyvinyl acetate is blended as a low profile agent relative to the resin component at a predetermined ratio. Aluminum hydroxide is blended relative to the resin component at a predetermined ratio.
