An embodiment of the present invention provides an induction heating apparatus comprising: a first coil unit having a first heating conductor, a second heating conductor and a first connecting conductor; a second coil unit having a third heating conductor, a fourth conductor and a second connecting conductor; a first shielding coil; and a second shielding coil. In the apparatus, one end of the first shielding coil is connected to one end of the first connecting conductor; the other end of the first connecting conductor is connected to one end of the second shielding coil; the other end of the second shielding coil is connected to one end of the second connecting conductor; and the other end of the second connecting conductor is connected to the other end of the first shielding coil such that the first shielding coil, the first connecting conductor, the second shielding coil and the second connecting conductor are connected to each other to form a ring-shape. Also, in the apparatus, one end of the first heating conductor is connected to one end of the first shielding coil; one end of the second heating conductor is connected to one end of the second shielding coil; one end of the third heating conductor is connected to the other end of the first shielding coil; and one end of the fourth heating conductor is connected to the other end of the second shielding coil. On the basis of an insertion space for conductive sheet, the first coil unit is located in one lateral direction and the second coil unit is located in the other lateral direction of the insertion space. |
