[Problem] An object of the present invention is to provide a motor control unit that achieves desired performance more simply with higher accuracy by setting a frequency characteristic according to a state of the control unit and automatically adjusting a control gain by the set value, and to provide an electric power steering apparatus equipped with the same. [Means for solving the problem] A motor control unit that comprises a current command value calculating section that calculates a current command value of a motor applying a steering assist torque to a steering system of a vehicle, and a feedback section that controls a motor current flowing to the motor through a feedback mechanism based on the current command value comprises: a control unit state detecting section that detects at least one state of the motor control unit, and outputs the state as a control unit state; and a characteristic changing section that changes a setting of a closed loop response characteristic of the feedback section in real time depending on the control unit state.
