Heat flow sensor using a thin film thermistor for heat flow sensor

摘要

PPROBLEM TO BE SOLVED: To provide an inexpensive heat flow sensor having excellent mass productivity, capable of predicting instantly and accurately a bottom temperature of a pan even from the back of a top plate of an induction heating cooking device, and a thin film thermistor for the heat flow sensor used for the heat flow sensor. PSOLUTION: The heat flow sensor is constituted of a heat receiving plate for absorbing heat of a detection object surface in contact with the detection object surface; the thin film thermistor for the heat flow sensor arranged on the opposite surface of a surface of the heat receiving plate in contact with the detection object surface so that a side face part on the side of one short side of an elongate substrate is in contact with the heat receiving plate; an elastic body arranged on a side face part on the side of the other short side of the elongate substrate oppositely to the heat receiving plate; and a case involving the thin film thermistor for the heat flow sensor and the elastic body, for holding the heat receiving plate.
