In an apparatus A in which electrode powderis allowed to adhere via the electrostatic force to an electrolyte membrane that serves as a substrateso as to form a catalyst layer, a screenis held in a state of non-contact with the substrateand a voltage is applied therebetween. The electrode powderis allowed to adhere to an elastic feed rollerand the feed rolleris allowed to rotate in contact with the screenby pressure. The electrode powderis dispersed toward the substrateso as to stably adhere thereto via both the electrostatic force and the extruding force of the elastic body. Variation of thickness and collapse of the outline are extremely reduced on the catalyst layer to be transferred and formed on the substrate (electrolyte membrane) via the electrostatic force using a conventionally used mesh-like screen so as to obtain a membrane electrode assembly with a high product manufacturing accuracy.
