<p>A protective device comprises a heating element (3) and a low-melting metal element (5) on a substrate (2), the low-melting metal element (5) being fused by the heat generated by the heating element (3), wherein the heating element (3) and the low-melting metal element (5) are stacked so as not to allow an insulating layer to intervene therebetween, whereby the protective device is miniaturized and the operating time reduced without lowering the rated current.</p> |
