PURPOSE: A temperature controller for a steering wheel using PTC element as a switch is provided to detect the temperature of the steering wheel without using a separate controller. CONSTITUTION: A temperature controller for a steering wheel comprises a steering wheel(100), a power supply unit(120), and a PTC thermistor(110). The steering wheel includes a heating element. The power supply unit supplies power to the heating element. The PTC thermistor switches on and off the power supplied to the heating element by the increase and the decrease of the temperature by adjusting of the resistance value.
