Abstract: The present invention aims to provide a thermosetting resin composition that causes no environmental issues such as generation of VOCs and has curability (especially, curability at low temperature) as good as that in the case using a diallyl phthalate monomer as a crosslinking agent. The present invention reveals that the following thermosetting resin composition has excellent curability at low temperature. The thermosetting resin composition contains an unsaturated polyester resin; an alicyclic polyfunctional allyl ester represented by the following formula (1) [in the formula, n is an integer of 2 to 4 and Z is an n-valent alicyclic hydrocarbon group]; and an initiator having a one-minute half-life temperature in a range of 100° C. to 250° C. and a molecular weight of 100 to 400 and selected from the group consisting of peroxyketals, peroxyesters, dialkyl peroxides, and peroxy carbonates.
