To increase the compression efficiency and compression performance of air by suppressing the rise of temperature on an intake passage side.
In this scroll air compressor, a passage block part 7 is formed integrally with the outer peripheral side of a fixed scroll 3. The passage block part 7 comprises an intake passage 17 one side of which is formed in a projecting pipe part 17A projecting to the outside and the other side of which is communicated with a compression chamber 16 on the outer diameter side, a discharge passage 19 communicating with a compression chamber 16 on the inner diameter side and discharging compressed air, and a supply and discharge passage 23 for supplying and discharging the compressed air from the discharge passage 19 to and from an air dryer 28. A discharging solenoid valve 27 positioned near the intake passage 17 and discharging (releasing) the discharge air discharged from the air suspension 33 side through the air dryer 28 from the projecting pipe part 17A of the intake passage 17 to the atmosphere is installed on the outer surface of the passage block part 7.
