PROBLEM TO BE SOLVED: To provide a microwave heating apparatus which normally performs uniform heating in the whole heating chamber, and according to a specific purpose, also performs locally concentrated heating. SOLUTION: The microwave heating apparatus comprises a microwave generating means 32, a waveguide 33, a heating chamber 34 to accommodate a heating object, a plurality of rotary antennas 38, 39 to irradiate microwaves, drive means 40, 41 to rotation-drive the rotary antennas, and a control means 411 to control the microwave generating means and the drive means. The control means has a timer 105 to measure an elapse time from a heating start and a plurality of control modes to control the drive means, and switches the plurality of control modes by the elapse time measured by the timer.
