This oil-cooled compressor 1 comprises a compressor body 10, an oil reservoir part 21, a motor 26, and bearings 41A, 42A. The compressor body 10 has a casing 13 that forms a rotor chamber 14 in which a screw rotor pair 12 is accommodated. Oil is stored in the oil reservoir part 21. The motor 26 includes a motor jacket 30 having a cooling flow path 31 through which the oil flows. The bearings 41A, 42A support the screw rotor pair 12. The oil-cooled compressor 1 further includes a first oil flow path 50 and a second oil flow path 60. The first oil flow path 50 supplies the oil from the oil reservoir part 21 to the rotor chamber 14 via the cooling flow path 31. The second oil flow path 60 branches off from the first oil flow path 50 between the oil reservoir part 21 and the motor jacket 30 to supply the oil to the bearings 41A, 42A.
