A torque sensor is configured to detect torque even when an abnormality has occurred in one magnetic sensor among multiple magnetic sensors. An electric power steering apparatus using the torque sensor is provided. The torque sensor includes a first magnetic sensor between a first magnetic collection mechanism and a second magnetic collection mechanism, a second magnetic sensor between the first and second magnetic collection mechanisms 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 between the first and second magnetic collection mechanisms and disposed at a same position as or a symmetric position to the magnetic environments of the first and second magnetic sensors. The torque sensor detects torque generated on a rotational member based on an output signal of the first, second, or third magnetic sensor.
