PROBLEM TO BE SOLVED: To provide a fluid controlling solenoid valve, preventing foreign matter contained in blow-back gas from an engine due to change with the passage of time from being deposited in a volume chamber through a communication hole formed in the valve or blocking up the communication hole. SOLUTION: This fluid controlling solenoid valve includes: a solenoid part 1 disposed in the interior of an intake pipe where the air flows to generate electromagnetic attractive force; a valve part 2 integrated with the solenoid part 1 and having a valve 10 brought into contact with and separated from a seat part 18 formed on the inner wall surface of the intake pipe by the electromagnetic attractive force; and a contractable bellows 12 constituting a volume chamber with the valve 10, communicated with the engine side through a communication hole 13 formed in the valve 10 and canceling the pressure difference between the upstream side and the downstream side of the valve 10. The valve part 2 is provided with air circulating means 11, 30 allowing air to flow from the upstream side to the downstream side of the valve 10 through the communication hole 13.
