Zusammenfassung:	In an evaporated fuel treatment apparatus including a bypass passage branching from an atmosphere passage and connected to a canister by detouring around at least one ii and a bypass valve to open and close the bypass passage, a controller holds the bypass valve in a closed state until an integrated purge flow rate reaches a predetermined value after start of purge control, the integrated purge flow rate being an integrated value of flow rate of purge gas flowing through a purge passage. When the integrated purge flow rate reaches the predetermined value, the controller turns the bypass valve to an open state.
