The present invention provides a temperature fuse (70, 80) provided with a cylindrical metal case (76), a sliding electrode (10) that can slide on the inner surface of the metal case (76), and a terminal (71, 78) that is electrically connected to the metal case (76) while in contact with the sliding electrode (10). When the temperature fuse operates, the sliding electrode (10) separates from the terminal (71, 78) and the electrical connection between the terminal (71, 78) and the metal case (76) is broken. The sliding electrode (10) is formed by processing a thin metal plate and is provided with at least a base material layer (21) made of copper or a copper alloy and a first surface layer (22) made of silver or a silver alloy. The thickness of the first surface layer (22) is 5 mum or greater at the location where contact is made with the terminals (71, 78). |
