Abstract
An induction heating cooking apparatus capable of performing wireless communication with an external apparatus includes a heating unit that inductively heats an object to be heated and a driving circuit that outputs electric power to the heating unit. Electric power output from the driving circuit during a period of time in which the wireless communication with the external apparatus is performed is less than electric power output from the driving circuit during a period of time in which the wireless communication with the external apparatus is not performed.
