Abstract (en)
[origin: EP0749132A1] The object is to provide a highly reliable positive temperature coefficient thermistor in which silver does not migrate even in hot and humid environments, and the first distinctive feature of the present invention is that it comprises first electrodes 2a, 2b, 3a, and 3b constituted of silver layers that are formed on both principal sides of the positive temperature coefficient thermistor 1 in such a way that the edges thereof recede inward from the outer rims of the positive temperature coefficient thermistor 1, and second electrodes 4a and 4b which contain aluminum and are formed in such a way as to cover the exposed surfaces of the first electrodes. <IMAGE>
