20. An induction heating type cooktop, comprising:
an upper plate coupled to a top side of a case and configured to place an object to be heated on a top of the upper plate;
a working coil disposed inside the case to heat the object;
a first thin film attached to a top surface of the upper plate;
a second thin film attached to a bottom surface of the upper plate;
an insulator disposed between the bottom surface of the upper plate and the working coil; and
a temperature sensor configured to measure a temperature of at least one of the first thin film, the second thin film, or the upper plate by a plurality of thermocouples,
wherein the plurality of thermocouples comprise an upper thermocouple connected to the first thin film and a lower thermocouple connected to the second thin film.
