PROBLEM TO BE SOLVED: To provide a torque sensor that can detect a torque if any one of magnetic sensors goes wrong, and an electrically-driven power steering device using the torque sensor.SOLUTION: The torque sensor includes: a first magnetic sensor between a first magnetism collecting mechanism and a second magnetism collecting mechanism; a second magnetic sensor between the first and second magnetism collecting mechanisms and in a position same as or opposite to in the magnetic environment of the first magnetic sensor; and a third magnetic sensor between the first and second magnetism collecting mechanisms and in a position same as or opposite to in the magnetic environments of the first and second magnetic sensors, and outputs a torque generated in a rotating member based on output signals from the first, second, and third magnetic sensors.SELECTED DRAWING: Figure 5

    【課題】 複数の磁気センサのうち1つの磁気センサに異常が発生したとしても、トルクを検出することができるトルクセンサおよびトルクセンサを用いた電動パワーステアリング装置を提供すること。【解決手段】 第一の集磁機構と前記第二の集磁機構の間に設けられた第一の磁気センサと、第一の集磁機構と第二の集磁機構の間に設けられ第一の磁気センサの磁気的環境と同じまたは対称位置に配置された第二の磁気センサと、第一の集磁機構と第二の集磁機構の間に設けられ第一の磁気センサおよび第二の磁気センサの磁気的環境と同じまたは対称位置に配置された第三の磁気センサと、を備え、第一の磁気センサ、第二の磁気センサ、または第三の磁気センサの出力信号に基づき回転部材に生じるトルクを検出するようにした。【選択図】 図5
