A motor control device includes a plurality of control units corresponding to a plurality of windings (14, 15) which is provided in a motor (12). The plurality of control units includes a master control unit (20), a slave control unit (30), and at least one abnormality monitoring unit (53, 62, 64). The slave control unit (30) is configured to generate a power supply control command value using information which is acquired through a path other than communication between the control units and which is held for use in control of supply of electric power to the windings (14, 15) in a normal state in which an abnormality in communication between the control units is not detected and to perform backup control for holding the power supply control command value until the abnormality monitoring unit (53, 62, 64) fixes an abnormality in communication between the control units after detecting the abnormality in communication.
