A compressor is provided to improve the space utilization and to prevent interference of each refrigerant pipe by contacting refrigerant pipes of first and second compression elements to an airtight container. A compressor(10) comprises an electric motor element(14) inside a sealed container, and first and second compression elements(32,34) driven by the electric motor element, and refrigerant pipes(92,94,96). The refrigerant pipes induce a refrigerant to the first compression element, refrigerant gas of intermediate pressure compressed from the first compression element to the second compression element, and discharge high pressure gas compressed from the second compression element. The refrigerant pipes of the first and second compression elements are contacted with an airtight container, and are processed toward the opposite direction from the airtight container.
