PURPOSE: A horizontal type scroll compressor is provided to be capable of improving a lubricating performance of bearing portions of a rotating shaft and suppressing temperature rise of the bearing portions. CONSTITUTION: An annular-shaped oil pressure space is formed on that portion of the rotating shaft, to which a discharge side of a spiral pump is opened, a sealing portion is provided between the oil pressure space and a high pressure space, and an oil discharge passage is provided for communication between the oil pressure space and an oil reservoir. Accordingly, the oil pressure space, to which an end of the spiral pump is opened, can be completely shut off from the high pressure space, and an oil in the oil pressure space can be discharged to and circulated in the oil reservoir, so that temperature rise between the rotating shaft and a main bearing and between the rotating shaft and the sealing portion can be suppressed.
