A radiation-curing resin composition that includes a resin component that includes an epoxy resin and/or oxetane resin having a naphthalene structure or a biphenyl structure, a boron-based diaryliodonium salt polymerization initiator represented by a specific formula at 0.005 to 0.5 mol per kg of the resin component, and a viscosity adjusting agent, the resin composition having a viscosity at 50° C. of at least 50 Pa.s, and a prepreg obtained by impregnating a fiber reinforcement with such a resin composition. This resin composition has excellent reactivity, and a prepreg formed from this resin composition and a fiber reinforcement is used for producing a composite material/member suitable for the aerospace field in particular.
