A vaporized fuel processing device includes a fuel tank storing fuel used for an internal combustion engine, a pressurizing portion performing a pressurizing process to increase an inner pressure of the fuel tank by supplying gas from outside to inside the fuel tank, and a controller controlling an operation of the pressurizing portion. The controller controls the pressurizing portion to perform the pressurizing process and to keep the inner pressure of the fuel tank at or above a predetermined pressure value at which vaporized fuel is prevented from flowing out of the fuel tank, except for a time of fueling of the fuel tank.
