Abstract

The present invention provides a heat-curable resin composition, which comprises (1) a heat-curable resin mixture comprising a heat-curable resin (a) and thickener particles (b) and exhibiting a viscosity (150° C.) after having been held at a temperature of 150° C. for 30 seconds that is a viscosity (S), and (2) a curing agent, and is characterized in that the heat-curable resin composition exhibits a lowest viscosity (R) at 80-120° C., the lowest viscosity (R) is 0.1-10 Pa·s, and the viscosity (S) and lowest viscosity (R) satisfy the relationship of formula (1):5<<200  formula (1).
