To provide a stator capable of suppressing turning up of a rolled insulating cap at an end of winding of the same.SOLUTION: The stator includes a roll-shaped first insulating cap (110) and a roll-shaped second insulating cap (120). One end of the first insulating cap (110) and one end of the second insulating cap (120) are bonded to each other. In a cross-section cutting the other ends of the first and second insulating caps (110, 120) in a plane including the axis of a stator core (10), an end-winding end (110a) of the first insulating cap (110), and an end-winding end (120a) of the second insulating cap (120) are located in a first area (A) between a first straight line (L1) passing through a center (O1) of the first insulating cap (110) and parallel to the axis of the stator core and a second straight line (L2) passing through a center (O2) of the second insulating cap (120) and parallel to the axis of the stator core (10).SELECTED DRAWING: Figure 10 【課題】ロール状の絶縁キャップの巻き終わり端部のめくれあがりを抑制できるステータを提案する。【解決手段】ステータは、ロール状の第１絶縁キャップ(１１０)と、ロール状の第２絶縁キャップ(１２０)とを備える。第１絶縁キャップ(１１０)の一端部と第２絶縁キャップ(１２０)の一端部とが接着されており、ステータコアの軸を含む平面で第１,第２絶縁キャップ(１１０,１２０)の他端部を切った断面において、第１絶縁キャップ(１１０)の巻き終わり端部(１１０ａ)と第２絶縁キャップ(１２０)の巻き終わり端部(１２０ａ)とが、第１絶縁キャップ(１１０)の中心(Ｏ１)を通りステータコア(１０)の軸と平行な第１直線(Ｌ１)と第２絶縁キャップ(１２０)の中心(Ｏ２)を通りステータコア(１０)の軸と平行な第２直線(Ｌ２)との間の第１領域(Ａ)内に位置する。【選択図】図１０
