Abstract
Disclosed is a microwave oven provided with: a heating chamber () for housing the object to be cooked therein; a magnetron () that oscillates by having a voltage applied thereto, and generates a microwave to be supplied to the heating chamber (); a radio wave sensor () for detecting the microwave generated by the magnetron (); a timer () for measuring an oscillation starting time that is a period of time from when the voltage is applied to the magnetron () to when the microwave is detected by the radio wave sensor () due to the oscillation; and a notification unit () for sending a notice about the timing at which the magnetron () should be exchanged. When the oscillation starting time becomes longer than a prescribed period of time, a notice about that fact is sent by the notification unit ().
