Abstract

An induction heating cooking apparatus includes a plurality of heating coils aligned in at least one row on a flat surface, a plurality of inverter circuits each configured to supply a high-frequency current to the corresponding one of the plurality of heating coils, and a controller configured to control driving of the plurality of inverter circuits. The plurality of heating coils include a first heating coil and a second heating coil that are adjacent to each other. The controller is configured to, when a material forming a heating target loaded on an upper part of the first heating coil is a magnetic material, and a material forming the heating target loaded on an upper part of the second heating coil at least includes a nonmagnetic material, set a frequency of the high-frequency current supplied to the second heating coil higher than a frequency of the high-frequency current supplied to the first heating coil.
