The present invention provides a fiber-reinforced resin intermediate material, including not only a thermoplastic resin but also a thermosetting resin, in which defects such as voids are difficult to be generated and which is excellent in shaping ability; and a method for manufacturing the same. The fiber-reinforced resin intermediate material according to the present invention is a fiber-reinforced resin intermediate material formed by attaching a resin to an outer surface part of a reinforcing fiber substrate formed of reinforcing fibers subjected to opening and heating the resin to a temperature equal to or higher than the melting point of the resin to impregnate the reinforcing fiber substrate with the resin, wherein the reinforcing fiber substrate has void space that is opened on an outer surface thereof and the resin is in a semi-impregnated state.
