Zusammenfassung:An electric power steering apparatus includes a torque sensor (9) including a first sensor element (91) and a second sensor element (92), a control unit (10), and a motor (5). When the first sensor element (91) and the second sensor element (92) are both normal, the first sensor output that is output by the first sensor element (91) and the second sensor output that is output by the second sensor element (92) have a predetermined correlation corresponding to a steering operation performed by a driver. When the first sensor element (91) or the second sensor element (92) is abnormal, the control unit (10) executes weighting with respect to the first sensor output and the second sensor output and calculates a steering torque on the basis of the weighted first sensor output and the weighted second sensor output.
