A temperature measurement circuit for measuring a temperature using a temperature sensitive element includes a voltage control circuit configured to apply a control voltage to the temperature sensitive element. The temperature measurement circuit includes a first switching circuit configured to switch levels of the control voltage based on a current flowing through the temperature sensitive element. The temperature measurement circuit includes a conversion circuit configured to convert the current flowing through the temperature sensitive element into a voltage level corresponding to the measured temperature, by using predetermined conversion gain. The temperature measurement circuit includes a second switching circuit configured to switch values of the conversion gain based on the voltage level.
