PROBLEM TO BE SOLVED: To provide a gas compressor improved in a function of separating compression gas from lubricating oil. SOLUTION: An oil separator 30, in which multiple gas passages 40 to 42 are formed by concentrically arranging a plurality of tubular bodies 31 to 33 each having a different diameter. A communicating portion 400 communicating to a gas compressor portion is formed to the outermost tubular body 31, communicating portions 410 communicating to the gas passages 40, 41 disposed on an inner and outer peripheral sides are formed to an intermediate tubular body 32, oil passing small holes 320 are formed in a wall of the intermediate tubular body 32, and oil drain holes 310 are formed in the outermost tubular body 31. Since the tubular gas passages are superposed and a passage into which gas flows in a whirl is made longer, the gas compressor whose separation performance of lubricating oil from compressed gas is improved is implemented.
