PROBLEM TO BE SOLVED: To provide a compressor preventing poor lubrication and damage or the like to each sliding part. SOLUTION: This compressor is provided with an oil separating means 5 separating oil from refrigerant compressed by a compression mechanism part 4, a drive part 3 driving the compression mechanism part 4 via a shaft 8, and a plurality of bearings 6, 7 bearing the shaft 8. A lubricating oil passage 30 and lubrication holes 30a, 30b for lubrication the bearings 6, 7 are included in the shaft 8. In the lubricating oil passage 30 in the shaft 8, at least an inner diameter of the lubricating oil passage 30 at an axial direction position where the lubrication hole 30b for the downstream side bearing 6 is set equal to or larger than an inner diameter of the lubricating oil passage 30 at an upstream side axial direction position.
