To provide an assembly method of an electric actuator and an assembly device of the electric actuator that can improve assembly performance.SOLUTION: An assembly method of an electric actuator includes: a first assembly step of making a second bearing 44b of a rotor assembly 40b hold a second bearing holding part 14a and assembling it to a second housing member 14; an attaching step of attaching an extension member 340 to the other side of a motor shaft 41 in a predetermined direction; and a second assembling step of assembling a first housing member 12 with a stator 43 fixed thereto the second housing member. In the second assembling step, the extension member has been attached to the motor shaft. The assembly method of the electric actuator further includes: a movement step of making the first housing member with the stator fixed thereto move to one side in the predetermined direction to bring the first housing member into contact with the second housing member in a state where the extension member is passed through a guide hole 32f penetrating the first housing member in a predetermined direction; and a fixing step of fixing the first housing member and the second housing member.SELECTED DRAWING: Figure 16 【課題】組立作業性を向上できる電動アクチュエータの組立方法、電動アクチュエータの組立装置を提供する。【解決手段】ロータアセンブリ４０ｂの第２ベアリング４４ｂを第２ベアリング保持部１４ａに保持させて第２ハウジング部材１４に組み付ける第１組立工程と、モータシャフト４１の所定方向他方側に延長部材３４０を取り付ける取付工程と、ステータ４３が固定された第１ハウジング部材１２を、第２ハウジング部材に組み付ける第２組立工程と、を含む。第２組立工程においては、モータシャフトに延長部材が取り付けられた状態である。第１ハウジング部材を所定方向に貫通するガイド孔３２ｆに延長部材が通された状態において、ステータが固定された第１ハウジング部材を所定方向一方側に移動させて、第１ハウジング部材と第２ハウジング部材とを接触させる移動工程と、第１ハウジング部材と第２ハウジング部材とを固定する固定工程と、を含む。【選択図】図１６
