Abstract
According to the present invention, a surface of a prepreg (104), said surface being provided with a partially fused structure (102A), and a surface of a metal member (110) are brought into contact with each other, and heat and pressure are subsequently applied thereto. After completely melting a resin containing a thermoplastic resin and adhering to the prepreg (104) so that a reinforcing fiber substrate (101) is impregnated with the molten resin, the resin is cured to obtain a matrix resin (105), thereby forming a CFRP layer (120) that serves as a fiber-reinforced resin material, and the CFRP layer is simultaneously compression-bonded to the metal member (110), so that a metal-CFRP composite body (100) in which the CFRP layer (120) and the metal member (110) are firmly bonded to each other is formed.
