An object of the present invention is to provide a torque sensor capable of detecting a torque even when an abnormality has occurred in one magnetic sensor among a plurality of magnetic sensors, and an electric power steering apparatus using the torque sensor. The torque sensor includes a first magnetic sensor provided between a first magnetic collection mechanism and the second magnetic collection mechanism, a second magnetic sensor provided between the first magnetic collection mechanism and the second magnetic collection mechanism and disposed at a same position as or a symmetric position to a magnetic environment of the first magnetic sensor, and a third magnetic sensor provided between the first magnetic collection mechanism and the second magnetic collection mechanism and disposed at a same position as or a symmetric position to the magnetic environment of the first magnetic sensor and a magnetic environment of the second magnetic sensor. The torque sensor detects a torque generated on a rotational member based on an output signal of the first magnetic sensor, the second magnetic sensor, or the third magnetic sensor.
