To provide a torque angle sensor and an electric power steering device that suppress an increase in the number of wires due to an increase in the number of detection parts.SOLUTION: A torque angle sensor of an electric power steering device includes: a driving rotating body that rotates together with a detection target; a driven rotating body that rotates together with a driving rotating body 30; torque detection units 81 and 82 that output signals corresponding to torque of the detection target and according to a magnetic field that changes as the driving rotating body rotates; an angle detection unit 90 that outputs a signal corresponding to a rotation angle of the detection target and according to a magnetic field that changes as the driven rotating body rotates; and a common wiring 74 that is connected to the torque detection units 81 and 82 and the angle detection unit 90 and outputs the signals from the torque detection units 81 and 82 and the signal from the angle detection unit 90.SELECTED DRAWING: Figure 7

    【課題】検出部の数の増加に伴う配線数の増加を抑制するトルクアングルセンサおよび電動パワーステアリング装置を提供する。【解決手段】電動パワーステアリング装置のトルクアングルセンサは、検出対象とともに回転する主動回転体と、主動回転体30とともに回転する従動回転体と、検出対象のトルクに対応し、主動回転体が回転することにより変化する磁界に応じた信号を出力するトルク検出部81、82と、検出対象の回転角度に対応し、従動回転体が回転することにより変化する磁界に応じた信号を出力する角度検出部90と、トルク検出部81、82および角度検出部90に接続されているとともに、トルク検出部81、82からの信号および角度検出部90からの信号を出力する共通配線74と、を備える。【選択図】図7
