Abstract
An unsaturated polyester resin composition includes a resin component containing an unsaturated polyester and a polymerizable monomer, an aluminum hydroxide, and an expandable graphite. The mixing ratio of the aluminum hydroxide to 100 parts by mass of the resin component is 50 parts by mass or more and 300 parts by mass or less. The mixing ratio of the expandable graphite to 100 parts by mass of the resin component is 3 parts by mass or more and 10 parts by mass or less. The expandable graphite has an average particle size of 150 μm or less.
