To provide an insulator capable of improving formability, a stator using this insulator, and an electric motor.SOLUTION: An insulator is mounted onto an annular core main body and a plurality of teeth projected along a radial direction from the core main body, and is for realizing insulation of the teeth and coils wound around the teeth, and the insulator includes teeth end surface coated parts 71 coating axial end surfaces of the teeth. The teeth end surface coated parts 71 are each provided to front surface 71a opposite to the tooth of the teeth end surface coated part 71, and each include: an inclination part 75 that is inclined so that a height from the axial end surface of the tooth is gradually changed along a radial direction, and an inclination part parallel part 95 and a teeth parallel part 96 that are provided to a back surface 71b of the tooth side of the teeth end surface coated part 71, and are recessed in a direction separating from the axial end surface of the tooth.SELECTED DRAWING: Figure 9B 【課題】成形性を向上できるインシュレータ、このインシュレータを用いたステータ及び電動モータを提供する。【解決手段】環状のコア本体及びコア本体から径方向に沿って突出される複数のティースに装着され、ティースとティースに巻回されるコイルとの絶縁を図るためのインシュレータであって、ティースの軸方向端面を覆うティース端面被覆部７１を有し、ティース端面被覆部７１は、ティース端面被覆部７１のティースとは反対側の表面７１ａに設けられ、ティースの軸方向端面からの高さが径方向に沿って漸次変化するように傾斜する傾斜部７５と、ティース端面被覆部７１のティース側の裏面７１ｂに設けられ、ティースの軸方向端面から離間する方向に窪んだ傾斜部平行部９５及びティース平行部９６と、を有する。【選択図】図９Ｂ
