Abstract: It is an object of the invention to provide an electric wire having an excellent electrical conductivity in use of the high melting point metal and being able to surely cut off by fusing the conductive material itself at a temperature lower than the melting point of the high melting point metal, even where heat is generated from flowing overcurrent in the electrical circuit. The electric wire of the invention has a feature including a conductive material formed of a first conductive member made of a low melting point metal, and a second conductive member made of a high melting point metal, which are provided adjacent to each other, wherein the conductive material is fused by erosion of the high melting point metal according to melting of the low melting point metal.

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.

Abstract: To provide a protection element evens the amount of flux on a fusible conductor and improves variations in fusing characteristics. A protection element is provided with: an insulated substrate; a heating body; an insulating member; two electrodes; a heating body internal electrode; a fusible conductor which is stacked over the two electrodes from the heating body internal electrode and fuses a current path between the two electrodes by heating; a flux coated on the fusible conductor so as to superimpose on the heating body; and a cover member attached to the insulated substrate covering at least the fusible conductor. The cover member has a cylindrical protrusion formed on an inner surface of the cover member so as to contact the flux, and a communication hole communicating with the inner surface side of the cover member from the protrusion is opened on a side wall surface of the cover member.
