Abstract
A hermetic compressor includes a housing which accommodates a motor and a compressing mechanism, an oil surface sensor mounted to a side wall of the housing, and refrigerating machine oil. The oil surface sensor is integrally formed of a detector for detecting a position of the oil surface of the refrigerating machine oil and a hermetic terminal. The hermetic terminal is placed at an end of a cylindrical tube having a smaller diameter than that of the housing, and the detector of the oil surface sensor is disposed inside the cylindrical tube.
