1. An induction heating cooking apparatus, comprising:
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 a corresponding one of the plurality of heating coils;
a material determiner configured to determine a material forming a heating target loaded on an upper part of each of the plurality of heating coils; and
a controller configured to control driving of the plurality of inverter circuits on a basis of a result determined by the material determiner, wherein:
the plurality of heating coils includes a first heating coil and a second heating coil that are adjacent to each other,
the material determiner makes a first determination that the heating target is loaded on the upper part of the first heating coil and the upper part of the second heating coil,
the material determiner makes a second determination that the material forming the heating target loaded on the upper part of the first heating coil at least includes a nonmagnetic material, and that the material forming the heating target loaded on the upper part of the second heating coil is a magnetic material, and
based on the material determiner making the first determination and the second determination, the controller is configured to:
set a frequency of the high-frequency current supplied to the first heating coil higher than a frequency of the high-frequency current supplied to the second heating coil, and
alternately switch an action between
an action of stopping supply of the high-frequency current to the first heating coil, and of supplying the high-frequency current to the second heating coil and
an action of stopping supply of the high-frequency current to the second heating coil, and of supplying the high-frequency current to the first heating coil.
