MANUFACTURING DEVICE FOR MEMBRANE ELECTRODE ASSEMBLY WITH SUBGASKET AND MANUFACTURING METHOD FOR MEMBRANE ELECTRODE ASSEMBLY WITH SUBGASKET

A bonding mechanism (5) adds a subgasket base material (9) including a subgasket film (92) to an electrode layer base material (8) including a membrane electrode assembly (85) with a first catalyst layer (83) provided on a surface of an electrolyte membrane (82). The bonding mechanism (5) includes: a first bonding roller (51) having an outer peripheral surface on which the electrode layer base material (8) is to be held; a second bonding roller (52) to hold the subgasket base material (9); a suction mechanism (53) that sucks the subgasket base material (9) on an outer peripheral surface of the second bonding roller (52); and a bonding roller movement drive part (54) that moves the second bonding roller (52) in an axis direction.
