ABSTRACT:
An electric conductor provided for decreasing a lifting force exerted on an object being heated has an aperture of a small diameter in the center thereof, which leaves a large surface area to enhance reduction of the lifting force. The electric conductor is also provided with a comb section around the aperture for preventing a circling current induced in the electric conductor from flowing into an area around the aperture. This structure can thus alleviate excessive heating around the aperture, and allow the heating coil to produce a high output power for a long duration of time even when an inwardly concaved pan is used.
