A protection element, comprising a heating element and the low-melting-point metal element that are formed on a substrate, the low-melting-point metal element being fused by heating of the heating element, wherein the section of at least part of the low-melting-point metal element is segmented into substantially at least two independent sections by providing at least two strips of low- melting-point metal element between a pair of electrodes that feed a current to the low-melting-point metal element. This protection element is shortened and stabilized in operating time. In addition, at least two strips of low-melting-point metal element are preferably provided between the pair of electrodes that feed a current to the low-melting-point metal element. It is also preferable to provide one strip of low-melting-point metal element slit at the center thereof between the pair of electrodes that feed a current to the low-melting-point metal element.
