An electric power steering apparatus is provided, which includes a steering torque sensor for detecting steering torque exerted on a steering system, a motor for exerting assist steering torque on the steering system, a motor current sensor for detecting drive current of the motor, a target current setting section for determining target current to be supplied for the motor based on the steering torque, a feedback control section for executing feedback control based on a deviation between the target current and the drive current of motor and a feedforward control section for executing feedforward control based on the target current. The apparatus has a feature that gain of the feedforward control is adapted to be greater as the speed of a vehicle increases.
