PROBLEM TO BE SOLVED: To provide a fluid supply device high in volume efficiency and compact while high in reducing effect for noises and vibration. SOLUTION: This fluid supply device 1 pressurizes fluid sucked from an inlet 4 and discharges it from an outlet 5. A perforated passage 10 is formed with facing at least an inlet part of a pressurizing chamber 11 for a passage inside a body between the inlet 4 and the pressurizing chamber 11. The perforated passage 10 which is a noise reducing member is contained in a casing 2 inside the body, thereby a special noise reducing member is not needed to be installed outside the casing 2 to make the device itself compact.
