<p>A novel protective device that has large capacity, being capable of sensing relatively low abnormal temperatures, and that has a simple structure and a small size. The protective device comprises (1) polymer PTC element (18) provided at its both-side major surfaces with metal electrodes (14, 16) and (2) shape-memory alloy lead (20), wherein the shape-memory alloy lead is connected to the polymer PTC element by means of conductive adhesive (22) containing a thermoplastic resin and a conductive filler.</p> |
