PROBLEM TO BE SOLVED: To provide a compressor retaining lubricating oil around a supply port and preventing refrigerant gas from entering an oil supply passage. SOLUTION: In a vane compressor 10, an oil reservoir chamber 31 is defined at an outside of an oil separator 40 in a discharge chamber 30, and an oil discharge port 42b making lubricating oil in the oil separator 40 flow down to the oil reservoir chamber 31 is formed and a gas discharge port 42a is formed in the oil separator 40. An oil supply passage 15d including a supply port 15e communicating to the oil reservoir chamber 31 at one end communicating to a compression mechanism C at another end is formed at a rear side plate 15 and the supply port 15e is positioned at a lower side than the oil discharge port 42b. A gas entrance prevention part 15f retaining lubricating oil around the supply port 15e and preventing entrance of refrigerant gas to the supply port 15e is extended to surround the supply port 15e at an end surface opposing to the discharge chamber 30 of the rear side plate 15.
