A fuel cell includes a membrane electrode assembly having electrodes disposed on both surfaces of an electrolyte membrane, a gas diffusion layer stacked on one surface of the membrane electrode assembly, a resin frame assembled onto the one surface of the membrane electrode assembly so as to surround the outer periphery of the gas diffusion layer apart from the outer periphery of the gas diffusion layer, and a resin sheet disposed between the gas diffusion layer and the resin frame, and the membrane electrode assembly so as to fill a space between the inner periphery of the resin frame and the outer periphery of the gas diffusion layer.

There is provided a technique of reducing the possibility of the occurrence of wrinkles in the process of bonding strip-shaped members to each other. A long strip-shaped first member is conveyed in a longitudinal direction of the first member. A width of a long strip-shaped second member in the shorter direction of the second member is larger than a width of the first member in a shorter direction of the first member. The second member is placed such that respective ends in a shorter direction of the second member are freed. The second member is bonded to the first member being conveyed, such that the shorter direction of the first member is aligned with the shorter direction of the second member and that respective ends in the shorter direction of the first member are placed between the respective ends in the shorter direction of the second member. The second member bonded to the first member is then conveyed along with the conveyed first member.
