Abstract
An induction heating apparatus includes: a core that has a pair of magnetic poles and transfers magnetic flux; a coil generating magnetic flux; conductors adjacently provided on both left and right sides of the magnetic poles; and lateral magnetic members formed of a magnetic material and arranged on an outer side of end portions of the object so as to extend along the end portions. The conductors shut off the magnetic flux that flows from a center portion of the heating object, taking a detour to the end portions, permit the magnetic flux to concentrate on the center portion, and accelerate temperature rise. The lateral magnetic members introduce the magnetic flux that propagates from one surface to the other surface, detouring around the end portions to thereby mitigate the magnetic flux density in the end portions and suppress overheating.
