To provide an electric actuator which enables improvement of rotation efficiency of an output shaft.SOLUTION: An electric actuator 10 includes: a motor part having a motor shaft which rotates around a center axis J1; a transmission mechanism connected to the motor shaft; an output shaft 61 which rotates around an output axis J3 parallel to the center axis; a first housing member 12 which rotatably supports the motor shaft and the output shaft from one axial side; a second housing member 14 which rotatably supports the motor shaft and the output shaft from the other axial side. A manufacturing method of the electric actuator 10 includes a step in which a first positioning part 71 provided at the first housing member and a second positioning part 72 provided at the second housing member overlap with each other when viewed from an axial direction and the first housing member and the second housing member are fixed to each other in a state where a jig 9 is inserted into the first positioning part and the second positioning part.SELECTED DRAWING: Figure 3 【課題】出力シャフトの回転効率を高めることができる電動アクチュエータを提供する。【解決手段】中心軸線Ｊ１を中心として回転するモータシャフトを有するモータ部と、モータシャフトに連結される伝達機構と、中心軸線と平行な出力軸線Ｊ３を中心として回転する出力シャフト６１と、モータシャフトおよび出力シャフトを軸方向一方側から回転可能に支持する第１ハウジング部材１２と、モータシャフトおよび出力シャフトを軸方向他方側から回転可能に支持する第２ハウジング部材１４と、を備える電動アクチュエータ１０の製造方法。第１ハウジング部材に設けられる第１位置決め部７１と、第２ハウジング部材に設けられる第２位置決め部７２とを軸方向から見て互いに重ね合わせ、第１位置決め部および第２位置決め部に治具９を挿入した状態で、第１ハウジング部材と第２ハウジング部材とを互いに固定する工程を有する。【選択図】図３
