ABSTRACT:
A heat sensitive portion is cooled when a temperature of an object to be measured is higher than the standard temperature while a heat sensitive portion is heated when a temperature of an object to be measured is lower than the standard temperature by Peltier's effect owing to an electric current passing through a thermopile from the outside. Thus, the sensitivity of a thermopile can be improved with a device which is simple and has an inexpensive construction.
