Zusammenfassung:	PURPOSE: To provide a method capable of manufacturing a dense CFRP molded product which is free from a pin hole. CONSTITUTION: In an oven or autoclave molding method laminating a prepreg comprised of a carbon fiber and thermosetting resin on a mold surface and hardening by heating under a vacuum bag, after arrangement of a film made of the prepreg or its resin component which is hardened at a low temperature on the mold surface, a prepreg forming a main structure hardening at a higher temperature than that of the low temperature hardening prepreg on the film and hardened by heating and pressurizing.
