The present invention relates to a method for measuring temperature using a thermistor, which can precisely measure the temperature above a thermoelectric device using a thermistor disposed on the thermoelectric device in a module for controlling the temperature of a component arranged on the thermoelectric device using the thermoelectric device. The method for measuring temperature using a thermistor according to the present invention involves electrically connecting the thermistor to an electrode pin via a thermoelectric device or a bridge submount attached to the thermoelectric device when electrically connecting the upper surface of the thermistor and the electrode pin, to thereby suppress the direct heat exchange between the thermistor and the electrode pin. Further, the method involves covering the thermistor with a polymer material, such as an epoxy having low thermal transmittance, to thereby effectively suppress the heat exchange between the thermistor and a package lid caused resulting from the gases in the package, thus enabling the thermistor to precisely measure the temperature of the thermoelectric device.
