Abstract
A polymer PTC element includes: an element body including a polymer and a conductive material dispersively mixed in this polymer; and a pair of electrode foils in each of which at least one surface is roughened and this surface is applied with an Au flash plating and which are bonded on both surfaces of the element body respectively with the roughened surfaces facing the element body. Therefore, electrical resistance in connecting portions of the element body and the electrodes is sufficiently lowered and the electrical resistance is not increased due to environmental and aging changes and so on.
