To provide a heating amount-measurement device which, relating to a heating device which uses both infrared ray heating and hot air heating, can measure respective heating amount separately.

A heating amount measurement device comprises a hot air sensing layer 4 which senses a hot air, a hat air/infrared ray sensing layer 3 which senses a hot air and an infrared ray, thermal resistance layers 2 and 2 thermally combined to the hot air sensing layer 4 and the hot air/infrared ray sensing layer 3, a temperature reference layer 1 thermally combined to the thermal resistance layers 2 and 2, a thermocouple 7 provided at the hot air sensing layer 4, a thermocouple 6 provided at the hot air/infrared ray sensing layer 3, and a thermo-couple 5 provided at the temperature reference layer 1. Based on a temperature difference T1 between the temperature detected with the thermo-couple 7 and that with the thermo-couple 5, a hot air heating amount is obtained, and based on a temperature difference T2 between the temperature detected with the thermo-couple 6 and that with the thermocouple 5, a hot air/infrared ray heating amount is obtained, and an infrared ray heating amount is obtained based on a temperature difference (T2-T1).
