Abstract: A protection element wherein variations in fusing characteristics are improved by making the amount of a flux applied on a fusible conductor uniform. The protection element includes: an insulating substrate; a heating element laminated on the insulating substrate and covered with an insulating member; first and second electrodes, formed at both ends of the insulating substrate; an internal heating-element electrode laminated on the insulating member so as to be superposed above the heating element; and a fusible conductor whose ends are connected to the first and second electrodes, and center portion of which is connected to the internal heating-element electrode. To both ends of the heating element, there are connected heating element electrodes to connect a power supply to generate heat by passing electric current through the heating element. In the fusible conductor, a depression portion opened upward is formed at a position to be superposed above the heating element.
