ABSTRACT:
A positive TCR thermistor device has excellent electrical contact between a heat generator and heat radiating blocks and high heat transfer efficiency therebetween. The positive TCR thermistor includes a heat generator having a positive temperature coefficient of resistance and heat radiating blocks supplying electric current to the heat generator and heating a heated medium by receiving heat generated by the heat generator. The heat generator is provided with a metallic paste electrode at a contact surface which is in contact with the heat radiating blocks and oil having flowability is disposed between the metallic paste electrode of the heat generator and the heat radiating blocks.
