Abstract: To realize a protection member that makes a flux amount applied on a fusible conductor uniform, and improves variation of fusing characteristics. The protection member includes an insulating substrate, a heating body, an insulating member, two electrodes, a heating body internal electrode, a fusible conductor layered from the heating body internal electrode to the two electrodes, and configured to fuse a current path between the two electrodes by heating, flux applied on the fusible conductor to superimpose with the heating body, and a cover member covering at least the fusible conductor and attached to the insulating substrate. The cover member further includes a plurality of cylindrical projection portions facing the heating body and formed on an inner surface of the cover member to be in contact with the flux.

Abstract: To provide a protecting device and a battery pack using the same, which are less likely to cause a spark even when a high voltage is applied and can safely and quickly interrupt the current path. A protecting device includes: an insulating substrate 2; a fuse element 3; a heat-generator 4 which generates heat to blow the fuse element 3; a heat-generator feeding electrode 5 which serves as a power-feeding terminal to the heat-generator 4; an insulating layer 6 which covers the heat-generator 4; and a heat-generator lead-out electrode 7 which is formed along the heat-generator 4 on the insulating layer 6 and holds the melted conductor 3a of the fuse element 3, wherein, when the heat-generator 4 is energized, the heat-generator feeding electrode 5 side thereof works as a high potential portion and the heat-generator lead-out electrode 7 side thereof works as a low potential portion, and in the heat-generator lead-out electrode 7, an overlapping area in which a distal end portion 7a extending in the high potential portion side of the heat-generator 4 overlaps the heat-generator 4 is smaller than an overlapping area in which a proximal end portion 7b extending in the low potential portion side of heat-generator 4 overlaps the heat-generator 4.

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.
