A membrane (1A) for fuel cell includes opposite surfaces, and an identifier (3). The identifier (3) exhibits an identifying property, and is disposed in at least a part of one of the opposite surfaces. The identifier (3) makes it possible to distinguish the front surface and rear surface of the membrane (1A), or the front and rear of an MEA (1) or fuel cell, which includes the membrane (1A). |
