Abstract

The thermosetting resin composition according to an embodiment of the present invention contains a component (A) which is a novolac vinyl ester resin having a hydroxyl group and an ethylenically unsaturated group in the molecule, a component (B) which is an ethylenically unsaturated monomer, and a component (D) which is a polyisocyanate compound, wherein the component (A) has a hydroxyl value of 30-150 mgKOH/g, and the mole number of the hydroxyl group with respect to the mole number of the ethylenically unsaturated group per gram of the component (A) ((the amount of the hydroxyl group [mol/g])/(the amount of the ethylenically unsaturated group [mol/g])) is 0.1-0.8.
