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.

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.
