Summary:To provide a stator of a rotary electric machine in which a winding in a slot is more securely fixed.SOLUTION: The stator includes: a stator core including an annular yoke and a plurality of teeth radially projecting from an inner circumferential surface of the yoke; a stator coil composed of a plurality of windings 20 wound around the teeth; and a foamed resin sheet 22 disposed along an inner wall of a slot 18 which is a space between the teeth. The plurality of windings 20 are arranged with gaps in a radial direction in the slot 18. A part of the foamed resin sheet 22 enters the gaps between the windings 20.SELECTED DRAWING: Figure 6 【課題】スロット内の巻線がより確実に固定された回転電機のステータを提供する。【解決手段】ステータは、円環状のヨークと、前記ヨークの内周面から径方向に突出する複数のティースと、を含むステータコアと、前記ティースに巻回される複数の巻線２０により構成されるステータコイルと、前記ティース間の空間であるスロット１８の内壁に沿って配される発泡樹脂シート２２と、を備える。前記複数の巻線２０は、前記スロット１８内において径方向に間隙を開けて並んでおり、前記発泡樹脂シート２２の一部は、前記巻線２０間の間隙に入り込んでいる。【選択図】図６
