PROBLEM TO BE SOLVED: To provide a temperature correction circuit without using an operational amplifier. SOLUTION: The temperature correction circuit includes: a temperature sensing resistor 11b whose resistance changes with a temperature change; and a fixed resistor 11a the temperature change in the resistance of which is smaller than that of the temperature sensing resistor 11b; one terminal of the fixed resistor 11a and one terminal of the temperature sensing resistor 11b are connected to an output terminal; a logic buffer 17a for fixing the other terminal of the fixed resistor 11a to a first potential of either of a power supply and ground; and a logic inverter 17b for fixing the other terminal of the temperature sensing resistor 11b to a second potential inverse to the first potential.
