1. A microwave treatment device comprising:
a heating chamber configured to accommodate a heating target;
a microwave generator configured to generate microwaves;
a heater including a heat source other than the microwaves and configured to heat an inside of the heating chamber;
a power feeder configured to supply the heating chamber with the microwaves;
a detector configured to detect reflected power from the power feeder; and
a controller configured to control output power of the heater and output power of the microwave generator,
wherein the controller is configured to cause the microwave generator to generate the microwaves in heating by the heater, the microwaves having output power such that the reflected power at a level detectable by the detector returns,
wherein the controller is configured to cause the microwave generator to provide a time zone in which the output power of the microwaves is set to be larger than the output power such that the reflected power at the level detectable by the detector returns, and
wherein the controller is configured to control the output power of the heater based on the reflected power detected by the detector when the output power of the microwaves is the output power such that the reflected power at the level detectable by the detector returns.
