Abstract: The present invention aims to achieve a Pb-free protection element by using a layered body including a high melting point metal layer and a low melting point metal layer. A protection element includes an insulating substrate, a heating body, an insulating member, two electrodes, a heating body extraction electrode, and a fusible conductor. Furthermore, the fusible conductor includes a layered body including at least a high melting point metal layer and a low melting point metal layer, and the low melting point metal layer is melted by a heat generated by the heating body, whereby, while eroding the high melting point metal layer, the low melting point metal layer is drawn close to the side of the two electrodes and the heating body extraction electrode, and fused, the two electrodes and the heating body extraction electrode each having high wettability for the low melting point metal layer.

Abstract: A protective element includes: a fuse element cuttable by energization in a first direction; a slider made of an insulating material, including: a plate-shaped portion extending in the first direction; a shielding portion erected in a second direction on the plate-shaped portion, having a shielding-portion through hole penetrating the shielding portion; and a case made of an insulating material, including a housing portion which houses a slider and a portion of the fuse element. The housing portion includes: a shielding-portion housing space which houses the shielding portion such that the shielding portion is movable in the second direction; and a plate-shaped-portion moving space which houses the plate-shaped portion such that the plate-shaped portion is movable in the second direction Prior to the fuse element being cut, the slider and the fuse element are housed such that the fuse element is inserted into the shielding-portion through hole.

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.
