PROBLEM TO BE SOLVED: To improve vibration resistance strength of a neutral line where a temperature sensor is arranged in a rotary electric machine stator.SOLUTION: A rotary electric machine stator 10 includes: neutral lines 16 and 18 for connecting neutral point-side ends of respective phase coils 14 which are inserted into a plurality of slots of a stator core 12 and are wound; a temperature sensor 30 installed in the neutral line 16; and a component cuff support 40 which has a protection shape section following a shape of the slot, is constituted of an insulator, and is arranged between the respective phase coils 14 and ends of the stator core 12 to be fixed. The component cuff support 40 arranged in a place where the temperature sensor 30 is disposed has an extension protection shape section which intrudes into a gap between a lower face of the temperature sensor 30 and an end face of the stator core 12 to be extended. An adhesion section 50 fixes the extension protection shape section of the component cuff support 40 and the temperature sensor 30. 【課題】回転電機ステータにおいて、温度センサが設けられる中性線の耐振動強度を向上させることである。【解決手段】回転電機ステータ１０は、ステータコア１２の複数のスロットに挿入されて巻回される各相コイル１４のそれぞれの中性点側端部の間を接続する中性線１６，１８と、中性線１６に設けられる温度センサ３０と、スロットの形状に沿う保護形状部を有し絶縁体で構成され、各相コイル１４とステータコア１２の端部との間に配置されて固定される部品カフサ４０とを備え、温度センサ３０が配置される箇所に配置される部品カフサ４０は、温度センサ３０の下面とステータコア１２の端面との間の隙間に侵入して延伸された延伸保護形状部を有し、接着部５０は、部品カフサ４０の延伸保護形状部と温度センサ３０との間を固定する。【選択図】図１
