description	To provide a rotary electric machine unit that can suppress increase in size of the rotary electric machine unit in the radial direction even when a current sensor becomes large sized or the number of the current sensors increases.SOLUTION: A rotary electric machine unit comprises: a rotary electric machine including a stator, a rotor rotating around a shaft relative to the stator, and more than one coil wound around the stator; and a power converter arranged side by side with the rotary electric machine in the axial direction along the axial center of the rotor. The power converter includes: more than one power module, each of which is electrically connected to each of the coils; more than one current sensor for detecting an output current from the power modules; and a fixing plate onto which the power modules are fixed. In the fixing plate, a cooling flow path in which a coolant flows is formed. At least part of the current sensors is arranged at a position overlapped with the cooling flow path in the axial direction.SELECTED DRAWING: Figure 5 【課題】電流センサが大型化、または電流センサの数が増加しても、回転電機ユニットの径方向における寸法の増加を抑えることが可能な回転電機ユニットを提供すること。【解決手段】回転電機ユニットは、固定子と、固定子に対して軸心回りに回転する回転子と、固定子に巻装される複数のコイルと、を有する回転電機と、回転子の軸心に沿った軸方向において、回転電機と並んで配置される電力変換装置と、を備え、電力変換装置は、複数のコイルとそれぞれ電気的に接続される複数のパワーモジュールと、複数のパワーモジュールからの出力電流を検出する複数の電流センサと、複数のパワーモジュールが固定される固定プレートと、を有し、固定プレートには、冷媒が流通する冷却流路が形成され、複数の電流センサの少なくとも一部は、軸方向において冷却流路と重なる位置に配置される。【選択図】図５
