Abstract: Provided is a protection circuit capable of reliably preventing an overcurrent or a sneak current after cutoff to improve safety, implementing cost reduction with a device configuration simpler than conventional device configurations, and further reducing a failure rate of a device. In a protection circuit, after one of two fuse elements provided in each of a plurality of protection elements is blown due to an overcurrent flowing along a current-carrying path, a heater provided in at least one of the plurality of protection elements generates heat due to a sneak current flowing via the plurality of protection elements on the current-carrying path which is remained and the current-carrying path which is remained is cut off due to destruction of the heater.

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.
