Abstract
An unsaturated polyester resin composition includes an unsaturated polyester, a polymerizable monomer, a low shrinkage agent, aluminum hydroxide, and an electrically conductive filler. The unsaturated polyester is a polymerization product of a polybasic acid including a polybasic acid having an ethylenically unsaturated double bond at a predetermined ratio and a polyhydric alcohol. A polyvinyl acetate as the low shrinkage agent is included at a predetermined ratio with respect to the total amount of the unsaturated polyester, the polymerizable monomer, and the low shrinkage agent. The aluminum hydroxide is included at a predetermined ratio with respect to the total amount of the unsaturated polyester, the polymerizable monomer, and the low shrinkage agent.
