Abstract: An induction heating type cooktop capable of heating both a magnetic body and a non-magnetic body with only a single coil and a capacitor without a separate switching structure is provided. The induction heating type cooktop includes an upper plate glass having a heating region formed so as to heat a cooking container; a working coil generating a magnetic field to heat the cooking container; and an inverter having a switch driven to allow current to flow in the working coil. The area of the working coil may be smaller than the area of the heating region.
