Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing a resin film joined body, which does not need a process for making the step difference of parts to be joined small and applying a light absorbent, and suppresses sticking of light absorbent as a foreign matter, and can efficiently join resin film members to each other to simply produce a resin film joined body.SOLUTION: The method for manufacturing the resin film joined body includes a process of butting edge surfaces of the resin film members to each other and joining the surfaces to produce the resin film joined body, wherein a light absorbing member provided with a surface having a high light absorptance with respect to the wavelength of a laser beam to be used and stability in the temperature environment of 300°C is used, the part at which the edge surfaces are butted to each other is brought into contact with the surface, the light absorbing member is irradiated with the laser beam to generate heat, the edge surfaces of the resin film members are thermally welded to each other and the butted part is separated from the light absorbing member to produce the resin film joined body.
