Abstract: The present invention provides a microwave heating apparatus and a heating method, capable of uniformly and effectively heating an object to be processed. The microwave heating apparatus (1) includes a phase control unit (7) configured to change a phase of a standing wave of a microwave introduced into a process container (2) by a microwave introduction unit (3). The phase control unit (7) includes a recessed portion recessed more than an inner surface (13b) of a bottom portion (13) of the processing container (2). The phase control unit (3) is formed of the bottom portion (13), and a fixing plate (27) installed at a lower surface of the bottom portion (13) from the outer side of the process container (2). The phase of the standing wave in the process container (2) is changed by the incidence and reflection of the microwave in the recessed portion of the phase control unit (7) surrounded by a metallic wall.
