Claim Text:
1. An electric power steering apparatus comprising: a detector that detects a value corresponding to a steering torque of a steering wheel; a correcting unit that corrects the detection value detected by the detector; and a target current calculating unit that calculates a target current which is supplied to an electric motor on the basis of the detection value corrected by the correcting unit, wherein the correcting unit makes a correction by using a correction value corresponding to the detection value detected by the detector so as to make a hysteresis between the detection value corrected by the correcting unit in one rotating direction of the steering wheel and the detection value corrected by the correcting unit in the other rotating direction of the steering wheel small in a case where an absolute value of the detection value detected by the detector is smaller than a predetermined value and large in a case where the absolute value is larger than the predetermined value, the detection value corrected by the correcting unit in the one rotating direction being obtained by correcting the detection value detected by the detector in the one rotating direction, the detection value corrected by the correcting unit in the other rotating direction being obtained by correcting the detection value detected by the detector in the other rotating direction.
