摘要： A PTC element has an element body in which an electroconductive filler is dispersed in a crystalline polymer, a pair of lead terminals compressed with the element body in between, and a protecting film covering a portion of the element body not compressed against the pair of lead terminals. Each of the pair of lead terminals has an overlap region overlapping with the element body, and a nonoverlap region not overlapping with the element body. An anchor projection embedded in the element body is formed in the overlap region of each of the pair of lead terminals. A peel prevention region for preventing peeling of the protecting film is formed in a region adjoining the element body in the nonoverlap region. The anchor projection is formed as crushed in a region except for at least the peel prevention region in the nonoverlap region.
