To provide an airtight terminal which can completely block intrusion of oil having low electric insulating property and whose current-carrying part is prevented from coming into contact with refrigerant/oil, and to provide a motor-driven compressor and a method for sealing a wiring part of the airtight terminal.SOLUTION: An airtight terminal includes: a lead member formed of a conductive material, an outer ring base which holds the lead member; an insulating material which insulates between the lead member and the outer ring base; and a cover member composed of an electric insulating material having the refrigerant resistance and the oil resistance fixed to at least one side of the outer ring base. The cover member includes: has an exposed part of the lead member; and a peripheral wall part surrounding the exposed part.SELECTED DRAWING: Figure 1 【課題】電気絶縁性が低いオイルのリードへの侵入を完全に遮断でき、気密端子の通電部が冷媒／オイルと接触しないようにした気密端子および電動圧縮機およびその気密端子の配線部封止方法を提供する。【解決手段】導電性材料により形成されたリード部材と、前記リード部材を保持する外環ベースと、前記リード部材と前記外環ベースとの間を絶縁する絶縁材と、少なくとも前記外環ベースの片面に固着した耐冷媒性および耐油性を有する電気絶縁材からなるカバー部材とを備え、前記カバー部材は、前記リード部材の露出部と、この露出部の周囲を取り囲んだ周壁部とを有する。【選択図】図１
