There is provided an electric power steering apparatus capable of alleviating an impact force at the time of an end contact, while giving natural and smooth steering feeling to a driver without degrading the steering feeling. When steering angle (¸s) is equal to or larger than a limit starting steering angle (¸st), a voltage target value (Vt) of an electric motor (13) is limited, and an upper limit (current limiting value I_Lim) of a current command value (Iref) is set based on the limited voltage target value (Vt) and the motor rotation speed (N) by use of a motor output characteristic of the electric motor (13). Then, the electric motor (13) is driven and controlled based on a current command value (Iref_Lim) that has been limited with the current command value (I_Lim).
