An abnormality monitoring device includes a control unit and a monitoring unit. The control unit includes a self-diagnosis circuit configured to perform a self-diagnosis processing during which other processing is inhibited. The monitoring unit includes an abnormality monitoring circuit and a reset circuit. The abnormality monitoring circuit is configured to perform an abnormality monitoring of the control unit. The reset circuit is configured to reset the control unit when the abnormality monitoring circuit decides an abnormality of the control unit. The abnormality monitoring circuit is configured to determine whether the self-diagnosis processing is finished, disable the abnormality monitoring of the control unit during the self-diagnosis processing, and start the abnormality monitoring of the control unit when the self-diagnosis processing is determined to be finished. Accordingly, the abnormality of the control unit is accurately monitored.
