It is an object of the present invention to improve the reliability of a compressor by appropriately measuring the temperature inside the compressor. A compressor pertaining to the present invention is equipped with a casing (10), a compression mechanism (15), a drive shaft (17), a main frame (23), a motor (16), a flow path forming member (91), and a temperature measuring mechanism (76). The casing stores lubricating oil in its bottom portion. The compression mechanism compresses refrigerant. The drive shaft drives the compression mechanism. The main frame has the compression mechanism placed on it and supports the drive shaft in such a way that the drive shaft may freely rotate. The motor drives the drive shaft. The flow path forming member forms an oil flow path (92). The oil flow path is a space located in the neighborhood of an inner peripheral surface of the casing and through which lubricating oil that lubricates sliding portions including the compression mechanism and the drive shaft flows. The temperature measuring mechanism is disposed outside the casing. The temperature measuring mechanism measures the temperature of a section of an outer peripheral surface of the casing positioned in the neighborhood of the oil flow path.
