PROBLEM TO BE SOLVED: To provide an electric motor which is capable of simultaneously preventing a stator and a housing from being dropped and rotated in simple configuration and is also improved in cost.SOLUTION: An electric motor 1 comprises: a stator 11 with which grooves 43a and 43b are formed on a side face by laminating and forming a core of an electromagnetic steel sheet including a recess in an outer periphery in an axial direction; and a tubular housing 3 in which the stator 11 is fitted. The stator 11 includes a fixing hole 42 with which the recesses are formed at intermediate positions in the axial direction by laminating the electromagnetic steel sheets at the intermediate positions differently from phases of the grooves 43a and 43b, and which has a predetermined length in the axial direction. The stator 11 is fixed into the housing 3 by a fixing member 40 inserted into the fixing hole 42 via a through-hole 41 that is provided on a side face of the housing 3.SELECTED DRAWING: Figure 1 【課題】簡単な構成でステータとハウジングの抜け止めと回り止めとを同時に可能とし、コスト的にも優れた電動モータを提供する。【解決手段】外周に凹部を有する電磁鋼板のコアを軸方向に積層形成することで側面に溝４３ａ，４３ｂが形成されたステータ１１と、内部に前記ステータ１１が嵌め込まれる筒状のハウジング３を有する電動モータ１において、前記ステータ１１は、軸方向中間位置において前記凹部を前記溝４３ａ，４３ｂの位相と異なるように前記電磁鋼板を積層することで当該中間位置に形成された、軸方向に所定の長さを有する固定孔４２を有し、前記ハウジング３の側面に設けられた貫通孔４１を通して前記固定孔４２に挿入される固定部材４０により、前記ステータ１１が前記ハウジング３に固定されている。【選択図】図１
