PROBLEM TO BE SOLVED: To provide a fuel supply device capable of reducing emission in exhaust. SOLUTION: A fuel supply device 1 includes an evaporation fuel storage tank 50 having a filter member 55, an evaporation fuel supply part 57 and an aggregated fuel discharge part 59. The filter member 55 segments an inner space of the evaporation fuel storage tank 50 into a first chamber 61 formed at a vertically upper side and a second chamber 62 formed at a vertically lower side of the first chamber 61. In the fuel injected from a sub-injector 42 into the first chamber 61, mist comprising a component having a high boiling point is aggregated while flowing in the filter member 55 downward from a vertically upper side, forming droplets on a lower face of the filter member 55 which are dropped into the second chamber 62 and discharged from the aggregated fuel discharge part 59 formed at a vertically lower side. Thereby, a component having a low boiling point can be separated from the component having a high boiling point, and the evaporation fuel can be efficiently supplied to an engine 10, thus achieving reduction in emission such as PMs (particulate matters).
