PROBLEM TO BE SOLVED: To provide a structure of mounting a temperature sensor of a stator, capable of effectively cooling a stator coil with a coolant, and measuring a temperature of a coil end.SOLUTION: In a stator coil 15A, a group of legs 21 at an outermost layer of one side coil end 30A in a radial direction are arranged to be tilted in a same circumferential direction. A main body 62 of a temperature sensor 60 is arranged below an axial line CL of a first stator 12A in a vertical direction, and is arranged along a circumferential direction at a lower side in a tilt direction of the group of legs 21 of the outermost layer in the radial direction. The temperature sensor 60 is brought into contact with an outer peripheral surface of the group of legs 21 to detect a temperature of one side coil end 30A. 【課題】冷媒によりステータコイルを効果的に冷却すると共に、コイルエンドの温度を測定可能なステータの温度センサ取付け構造を提供する。【解決手段】ステータコイル１５Ａは、一方のコイルエンド３０Ａの径方向最外層の脚部２１群が、同一周方向に傾斜して配列され、温度センサ６０は、第１のステータ１２Ａの軸線ＣＬよりも鉛直方向下方、且つ、径方向最外層の脚部２１群の傾斜方向下側に本体部６２が周方向に沿って配置され、脚部２１群の外周面に接触して一方のコイルエンド３０Ａの温度を検出する。【選択図】図３
