A front terminal plate (31) that is joined to a fuel cell unit (40) at the front end of a fuel cell stack has a metal-plating layer (31b) formed on the side to be joined to the fuel cell unit (40). The metal-plating layer (31b) is formed so as to cover the surface of a plate (31a), and the surface of the metal-plating layer (31b) is flat. The thickness of the metal-plating layer (31b) in an electrode-facing region (31c) that faces an electrode region of the fuel cell unit (40) is different from the thickness of the metal-plating layer (31b) in a peripheral region (31d) that surrounds the electrode-facing region (31c), and the thickness of the metal-plating layer (31b) in the peripheral region (31d) is larger than the thickness of the metal-plating layer (31b) in the electrode-facing region (31c). |
