The evaporative fuel processing system includes a fuel tank, a canister, a pump, a pressure detection unit, a temperature detection unit, and a leak diagnosis unit a leak diagnosis unit configured to diagnose leak in the diagnostic object based on a first pressure change which is a change in pressure detected by the pressure detection unit when the temperature in the diagnostic object changes, a second pressure change which is a change in pressure detected by the pressure detection unit when the inside of the diagnostic object is pressurized or depressurized by the pump, a detected temperature by the temperature detection unit, a first preparation information and a second preparation information.
