The electrode-membrane-frame assembly includes a polymer electrolyte membrane, an electrode portion, a first frame body, a second frame body, and a third frame body. In the first frame body and the second frame body, a portion that is in contact with any one of the gaskets is formed in a plane without a joint or a step difference. The first frame body is disposed at a peripheral edge portion of the polymer electrolyte membrane. The second frame body is disposed on a surface opposite to a surface of the polymer electrolyte membrane with which the first frame body is in contact, and sandwiches the polymer electrolyte membrane together with the first frame body. The third frame body seals a boundary surface between the first frame body and the second frame body.
