A compressor for suppressing leakage of lubricating oil has a casing, a motor and a scroll mechanism coupled to the motor by a drive shaft. The drive shaft is rotatably supported by a bearing. The lubricating oil is supplied between the drive shaft and the bearing. An oil collecting portion is formed at an end portion in the axis direction of a bearing portion. The bearing portion is constituted of an outer peripheral surface of the drive shaft and an inner peripheral surface of the bearing. The oil collecting portion includes an oil groove formed in the periphery direction of the drive shaft. An oil passage is formed to conduct the lubricating oil into the oil collecting portion.
