Abstract: The problem to be solved by the invention is to provide a method for producing a joined body that reduces springback and can maintain high joining strength. The above problem is solved by a method for producing a joined body. The method includes heating a contact expected surface (a) of a molded body (A) containing carbon fibers and a thermoplastic resin, brining the heated contact expected surface (a) into contact with a contact expected surface (b) of a molded body (B) containing a thermoplastic resin; and joining the molded body (A) and the molded body (B). Contact surfaces (c) formed by contacting the contact expected surface (a) with the contact expected surface (b) includes a three-dimensional curved surface. The contact expected surface (a) is heated by using an infrared radiation mechanism capable of selectively infrared radiating the contact expected surface (a).
