Abstract:
1. A resin composition comprising, as essential components, 100 parts by mass of a component (A) which is an epoxy resin, 41 to 80 parts by mass of a component (B) which is thermoplastic resin particles, and 20 to 50 parts by mass (in terms of diaminodiphenylsulfone) of a component (C) which is diaminodiphenylsulfone microencapsulated with a coating agent, wherein the thermoplastic resin particles (B) comprise at least thermoplastic resin particles (B 1 ) having an average particle diameter of 1 to 50 μm and thermoplastic resin particles (B 2 ) having an average particle diameter of 2 to 100 μm at a mass ratio of 3:1 to 1:3 and the average particle diameter ratio D 2 /D 1 of the average particle diameter D 2 of the thermoplastic resin particles (B 2 ) to the average particle diameter D 1 of the thermoplastic resin particles (B 1 ) is 2 or more.
