。[Claims for Utility Model Registration] A positive temperature coefficient thermistor comprising a positive temperature coefficient thermistor body, electrodes formed on both main surfaces of the positive temperature coefficient thermistor body, and a pair of lead terminals joined to the electrodes by solder. In the element, at least one of the lead terminals is provided with a current fuse portion formed to be relatively narrower than the remaining portion of the lead terminal, and at least one of the lead terminals is bonded to an electrode. A positive temperature coefficient thermistor element with a fuse function, wherein the solder is made of a material that can be melted by a rise in temperature of the positive temperature coefficient thermistor element due to an overvoltage exceeding the withstand voltage of the positive temperature coefficient thermistor element.
