Claim 17:
18. A hermetic terminal comprising:
a metal base that is provided with at least one sealing hole;
a lead that is inserted in the sealing hole provided on the metal base;
an insulating material that hermetically seals the metal base and the lead; and
a heat insulating member that is provided to cover at least a partial surface of the hermetic terminal which is located inside a pressure-resistant container after the hermetic terminal is fixed to the pressure-resistant container and comes into contact with refrigerant sealed in the pressure-resistant container; wherein
the heat insulating member includes a portion that extends along at least a surface of the lead located inside the pressure-resistant container and covers the lead except a tip end thereof;
the portion of the heat insulating member that covers the lead is provided with an annular projection that surrounds an outer circumference of the heat insulating member; and
the annular projection has an outer diameter that matches an inner diameter of a connector which is connected to a wiring cord of an electric motor arranged inside the pressure-resistant container so as to prevent refrigerant and lubricating oil from entering inside the connector.
