According to a scroll compressor of the present invention, a vertical groove is formed in the journal such that the vertical groove has a predetermined length measured from an upper end of the journal, a first oil supply hole and a second oil supply hole which are in communication with the main shaft oil supply hole and which open from the vertical groove are formed, a first opening of the first oil supply hole is located on a side of a lower end of the vertical groove, and a second opening of the second oil supply hole is located on a side of an upper end of the vertical groove. According to this configuration, an amount of oil supplied to the bearing can be increased, damage of the bearing can be reduced, and cooling ability and COP can be enhanced.
