- a cured product of a thermosetting resin composition;
- and continuous reinforcing fibers, and
- wherein the thermosetting resin composition is an epoxy resin composition comprising an epoxy resin (A) and an epoxy resin curing agent (B), the epoxy resin curing agent (B) comprising a reaction product of:
- a component (x1);
- and a component (x2) described below:
- (x1) at least one selected from the group consisting of meta-xylylenediamine and para-xylylenediamine, and
- (x2) at least one selected from the group consisting of unsaturated carboxylic acids represented by General Formula (1) below and derivatives thereof;
- where in Formula (1), R1 and R2 each independently represent a hydrogen atom, an alkyl group having from 1 to 8 carbons, an aryl group having from 6 to 12 carbons, or an aralkyl group having from 7 to 13 carbons.
