Abstract:
A PTC thermistor comprising:a laminated body containing at least two layers of conductive sheet composed of a polymer having a PTC characteristic and at least one layer of inner-layer electrode composed of a metallic foil having first plated layers on both surfaces, said laminating body formed by alternately laminating a plurality of layers so that said inner-layer electrode fails to extend to one side end portion and that the outermost layer is said conductive sheet,an outer-layer electrode separated from said inner-layer electrode of said conductive sheet by said conductive sheet, said outer-layer electrode positioned at the outermost layer of said laminated body, having a space in part, and having a second plated layer separating said outer-layer electrode from said conductive sheet,side-face electrode layers disposed only in recesses at sides of said laminated body for connecting electrically said inner-layer electrode and outer-layer electrode.
