1. An electric range, comprising:
a cover plate on which a heating target is disposed;
a heater comprising a working coil to which high-frequency power is applied and configured to heat the heating target using a magnetic field generated from the working coil;
a plate temperature sensor disposed in the heater and configured to sense a temperature of the cover plate; and
a coil temperature sensor disposed in the heater and configured to sense a temperature of the working coil, wherein the heater further comprises a sensor bracket that is disposed in a through hole of the heater and supports the coil temperature sensor under the working coil, wherein the sensor bracket comprises a hole to which the coil temperature sensor is forcedly fitted, wherein the coil temperature sensor comprises:
a sensor body having an upper surface forming a sensing surface that is in contact with a lower surface of the working coil; and
an elastic cover disposed on a lower surface of the sensing surface and at least partially covering an outer surface of the sensor body, and wherein when the coil temperature sensor is coupled to the hole, the elastic cover is pressed by an inner circumferential surface of the hole and elastically deformed.
