A protective device (1) comprises a fuse element (4) provided to electrodes (3a,3b,3c) on a substrate (2). The fuse element (4) has a liquidus point higher than the mounting temperature of the protective device (1), and has a solidus point lower than the mounting temperature of the protective device. The difference between the liquidus and solidus points is 5 DEG C or higher. <IMAGE> |
