PROBLEM TO BE SOLVED: To prevent a characteristic defect caused by thermal deterioration resulting from soldering or welding by connecting a lead terminal to a polymer PTC element main body without directly imparting heat in soldering or welding thereto in the case of connection. SOLUTION: The electrode of a lead terminal 3 is bonded to a polymer PTC element main body 1 without imparting heat of soldering or welding to the polymer PTC element main body 1. Therefore, metal foil 2 that becomes the electrode is bonded and integrated to the lead terminal 3 in advance, and a mounting surface of the metal foil 2 is then bonded to the PTC element main body 1. The mounting surface of the metal foil 2 is roughened in advance. COPYRIGHT: (C)2004,JPO&NCIPI
