Abstract:
A thermistor chip comprising:a planar thermistor chip element having a pair of main surfaces, a pair of mutually oppositely facing end surfaces extending between said main surfaces and a pair of side surfaces extending between said main surfaces and between said end surfaces; anda pair of electrodes, each including a single first metal layer, a second metal layer and a third metal layer, said first metal layer being formed directly on one of said end surfaces and end portions of said main surfaces adjacent the one end surface, said second metal layer being formed over said first metal layer, said third metal layer being formed over said second metal layer, the first metal layers of said electrodes on each of said pair of main surfaces having mutually opposite edges which face and are separated from each other and are not overlapped by the second metal layer;wherein at least one of said electrodes further includes a fourth metal layer which is formed over the edge of said first metal layer on at least one of said main surfaces of said thermistor chip element and extends so as to directly contact said one main surface of said thermistor chip element.
