PROBLEM TO BE SOLVED: To provide a compressor capable of reducing the vibration and noise of an existing compressor by a simple method by changing the natural frequency of a hermetic case to prevent a resonance phenomenon of the compressor and by preventing the vibration and noise at the high-speed rotation of the compressor from being maximized. SOLUTION: In the compressor provided with the hermetic case 10 forming an inner structure, a drive part provided in of the hermetic case 10 and generating drive force compressing fluid, and the inner structure including a compression part compressing fluid, the hermetic case 10 is provided with a weight 50 having predetermined mass for reducing vibration and noise generated by the inner structure.
