Abstract: An induction heating type cooktop includes a cover plate, a working coil, a thin film, an additional metal film, and an insulator. The cover plate is coupled to a top of a case and includes an upper plate configured to place an object to be heated. The working coil is disposed in the case and configured to heat the object. The thin film is disposed on the upper plate. The additional metal film forms an equivalent circuit with the thin film and the object so as to allow an induced current by the working coil to be induced into the object arranged at the upper plate. The insulator is disposed between a bottom surface of the upper plate and the working coil.
