A control device is used in a motor device including a motor, an inverter that drives the motor, a cooling device that cools the inverter with a cooling medium, and a current sensor mounted on a connection line connecting the motor and the inverter, and the control device is configured to control the inverter. The control device includes an electronic control unit configured to derive an estimated temperature that is an estimated value of a temperature of the current sensor, based on a coil temperature and a cooling medium temperature, and to limit power output from the motor based on the estimated temperature, the coil temperature being a temperature of a coil of the motor, and the cooling medium temperature being a temperature of the cooling medium.
