PURPOSE: A compressor including a noise reduction structure is provided to reduce the noise by opening an exhaust valve with compressed air and by performing only an opening and closing operations of the exhaust valve in a compressed air process. CONSTITUTION: A compressor(100) including a noise reduction structure comprises a check valve, a cylinder(130), a piston(135), and a driving unit(180). The driving unit drives the piston. The check valve performs the opening and closing operations in a one way direction on an upper part and is connected to a storage tank. The upper part of the piston is located lower than the upper part of an inhalation hole(133) where the piston is on the bottom dead center. The upper part of the piston is located higher than the upper part of the inhalation hole when the piston is on the dead center.
