Abstract
A thermistor device manufactured at low cost in which atoms of Ag do not migrate substantially into the thermistor body. The device comprises a disk-like thermistor body and annular first electrodes formed in peripheral portions of the front and back surfaces, respectively, of the thermistor body. The first electrodes are made from a conductive material not containing silver. Second electrodes are formed in central portions of the front and back surfaces, respectively, of the thermistor body. The second electrodes are in ohmic contact with the thermistor body, and are made from a conductive material made mostly of silver.
