An electric power steering apparatus (1) includes an EPS actuator (10) that applies assist force to a steering system, and an ECU (11) that controls operation of the EPS actuator (10). The ECU (11) includes an inverter device (32), a gate driver circuit (31), a gate driver power source (29), a microcomputer (16), and the like. The microcomputer (16) switches assist control to assist stop control, based on an indication of a voltage decrease in the gate driver power source (29).
