PROBLEM TO BE SOLVED: To suppress the occurrence of hydrolysis in an insulation member.SOLUTION: A motor includes a rotor arranged inside, a stator arranged outside, a conductor wire wound on the stator, and the insulation member arranged between the conductor wire and the stator. Refrigerant is R32 refrigerant, mixed refrigerant including the R32 refrigerant, HFO1123 refrigerant, or mixed refrigerant including the HFO1123 refrigerant. The insulation member has a substrate formed by a first resin material having ester linkages, or a substrate formed with the first resin material and a second resin material having no ester linkages and laminated thereon. On the surface of the substrate, a watertight coating layer is formed.SELECTED DRAWING: Figure 3 【課題】絶縁部材に加水分解が生じることを抑える。【解決手段】モータは、内側に配置されたロータと、外側に配置されたステータと、ステータに巻かれた導線と、導線とステータとの間に配置された絶縁部材と、を有する。冷媒は、Ｒ３２冷媒、Ｒ３２冷媒を含む混合冷媒、ＨＦＯ１１２３冷媒、ＨＦＯ１１２３冷媒を含む混合冷媒のいずれかである。絶縁部材は、エステル結合を有する第１の樹脂材によって形成された基材、または第１の樹脂材にエステル結合を有していない第２の樹脂材を積層して形成された基材を有し、基材の表面に、耐水性を有する被覆層が形成された。【選択図】図３
