PROBLEM TO BE SOLVED: To reduce the size and increase the cooling performance of a compressor by cooling a discharge pipe and an aftercooler by a cooling air by which a compressor body has been cooled. SOLUTION: The compressor body 4, a motor 14, and a tank 17 are stored in a soundproof box 1. A partition plate 26 and a box body 29 are disposed at the rear of the compressor body 4. The discharge pipe 18 and the aftercooler 19 are disposed in the storage space 29D of the box body 29. During the operation of the compressor, the cooling water by which the compressor body 4 has been cooled flows into the storage space 29D of the box body 29 through the inflow opening 30 of the partition plate 26, and the discharge pipe 18 and the aftercooler 19 are cooled by the cooling air. Since the temperature of compressed air can be efficiently lowered by effectively utilizing the cooling air, the cooling performance of the aftercooler 19 can be increased while reducing the size thereof.
