To solve a problem of imparting an uncomfortable feeling to a user due to generation of a beat sound based on the difference in an operating frequency when driving a plurality of induction heater coils.
This induction heater cooker has the induction heater coils for generating a magnetic flux for inductively heating the heatable tableware, inverters for constituting a resonance circuit including the induction heater coils, and generating a high frequency current, a control part for simultaneously controlling the drive of a plurality of inverters, and an operation part for setting heater output of the inverters. The control part is constituted for driving the plurality of inverters in time sharing, and enhancing the heater output at respective inverter drive time more than preset output so that average output of the respective inverters obtained by time sharing driving becomes the output set by the operation part.
