ABSTRACT:
A temperature sensor comprises a thermistor element, a metal tube into which the thermistor element is inserted, two electrode wires joined to the thermistor element, two lead wires, which are covered by covering tubes with uncovered portions remaining and joined to the electrode wires, respectively, at the uncovered portions, and a housing having an inner hollow space into which the electrode wires and the lead wires are accommodated together with a resin. The sensor further comprises an insulating case disposed inside the housing and provided with a partition section for separating the joined portions of the electrode wires and the lead wires, the electrode wires and the lead wires from each other, and the inside of the insulating case is filled up with resin in a state that an opened end of the metal tube, the electrode wire and portions of the covered lead wires and uncovered portions thereof are inserted in the insulating case.
