PROBLEM TO BE SOLVED: To provide a fuel vapor processing system capable of securing a processing quantity of fuel vapor, with a simple constitution, even in a supercharging engine. SOLUTION: This fuel vapor processing system 300 comprises a canister 301 for temporarily storing and discharging the fuel vapor generated in a fuel tank 201, an air flow passage 307 for returning a part of pressurized air delivered by a supercharger 104 for pressurizing air sucked in the engine to the suction port side of the supercharger 104, a pump part 308 arranged in the middle of an air flow passage 307, generating negative pressure by squeezing an air flow in the air flow passage 307 and introducing the fuel vapor discharged by the canister 301 into the air flow passage 307 by using this negative pressure.
