An electric power steering apparatus including a steering torque detecting section configured to detect a steering torque applied to an operation member for steering a vehicle, a steering state judging section configured to determine whether forward stroke steering that steers the operating member away from a steering angle midpoint is performed, a motor controlling section configured to control the driving of an electric motor based on the steering torque detected by the steering torque detecting section, and a phase compensating section provided in the motor controlling section for performing phase compensation, such that, when the forward stroke steering is not performed according to the steering state judging section, a gain in a predetermined frequency band in frequency response characteristics of the phase compensation is lower than gains in frequency bands lower and higher than the predetermined frequency band, and is lower than a gain in the predetermined frequency band when the forward stroke steering is performed.
