Abstract: An electric range is provided that may include an elastic holder to fix a fuse and a sensor in a central portion of an induction heating unit disposed over/on/in an upper portion of a base plate, thereby stably fixing the fuse and sensor against external impact. In the electric range, an upper end of the sensor may come into close contact with a lower surface of a cover plate disposed over/on/in an upper portion of the induction heating unit, thereby stably measuring a temperature of the cover plate and absorbing an external impact.
