PROBLEM TO BE SOLVED: To provide an evaporated fuel treatment device for effectively utilizing an adsorbing material in a canister. SOLUTION: A vapor flow-in hole 30, an air hole 34 and a negative pressure introduction hole 32 are provided in the canister 10 which has the adsorbing material 12 inside. The vapor flow-in hole 30 is communicated with a fuel tank via a conduit 40. The negative pressure introduction hole 32 and the air hole 34 are communicated with a conduit 42 and a conduit 44, respectively. The conduit 42 and the conduit 44 are communicated with a conduit 46 via a valve 50. The conduit 46 is communicated with the air. A temperature sensor 54 is provided near the air hole 34. During non-execution of purge, the conduit 44 is communicated with the conduit 46 until the adsorption of evaporating fuel is determined by the temperature sensor 54. After the adsorption of the evaporated fuel is detected by the temperature sensor 54, the conduit 42 is communicated with the conduit 46 and the conduit 44 is cut off the conduit 46.
