Abstract: There is provided a technique that readily performs positioning of a joining member relative to a strip member during conveyance. A joining device 100 joins a gas diffusion layer 7 with a first catalyst electrode layer 2 of a strip body 5r which is a continuous strip member of a membrane electrode assembly 5, while conveying the strip body 5r. A controller 101 of the joining device 100 obtains a detection time td based on a detection signal of a catalyst layer detector 130 when a front end 3e of a second catalyst electrode layer 3 placed on the strip body 5r passes through a detection point DP. The controller 101 subsequently obtains a joining position reach time tt based on the detection time td when the gas diffusion layer 7 reaches a press point PP of joining rollers 152. The controller 101 starts conveying the gas diffusion layer 7 by means of a transfer at a conveying start time ts that is obtained based on the joining position reach time tt and a specified speed pattern of the transfer 141.
