PROBLEM TO BE SOLVED: To provide a new temperature detecting module and a new temperature detection method that dispense with electronic circuits for comparing and determining detected temperatures and that can detect temperature, by using a simple circuit configuration, by noticing the reversal of thermoelectromotive force in a semiconductor that has been overlooked in prior art, and to provide a heating/cooling module and a temperature control method that keeps the temperature constant. SOLUTION: A thermoelement having characteristics for reversing the thermoelectromotive force, generated according to the temperature difference between both the surfaces at prescribed temperature, a control element for turning on/off the flow direction of current, and a notifying element are connected in series to report that current has flowed and flow temperature has been reached, when the direction of electromotive force has changed. Constant surface temperature is maintained, by allowing a direct current to flow to the thermoelement which has these characteristics. COPYRIGHT: (C)2009,JPO&INPIT
