PROBLEM TO BE SOLVED: To provide a compressor having an expansion mechanism part for reducing a heat transfer loss. SOLUTION: This compressor is composed of a sealed vessel 42 for storing the expansion mechanism part 1, a compression mechanism part 41 and an electric motor part 2. The compressor is characterized in that the expansion mechanism part 1 forms an expansion chamber 15 between both by meshing a fixed scroll 12 and a turning scroll 13 having a spiral lap rising from an end plate, and performs suction and delivery by moving while changing the volume in the expansion chamber 15 when turning the turning scroll 13 along a circular orbit under regulation of rotation by a rotation regulating mechanism 14, and a scroll expansion mechanism part constitutes a part of the contour of the sealed vessel 42 by the end plate of the fixed scroll 12.
