PROBLEM TO BE SOLVED: To provide a fuel supply device surely maintaining a state of a suction cylinder part for sucking fuel into a fuel pump positioned in the fuel. SOLUTION: This fuel supply device 100 includes: a housing 60 forming a combustion chamber 51; a fuel pump 40 sucking the fuel inside of the fuel chamber 51; a suction cylinder part 53 positioning inside the fuel chamber 51, into which the fuel to be sucked into the fuel pump 40 flows; and a suction filter 70 for filtering the fuel flowing into the fuel chamber 51. In the bottom 73 of the housing 60, a plurality of barrier parts 75a-75f extending at a length less than a circumference of the suction cylinder part 53 are provided to stand around the suction cylinder part 53 to surround the suction cylinder part 53. Each barrier part 75a-75f is arranged so that at least one of them is positioned in all the radial direction of the suction cylinder part 53, being arranged so that both ends thereof in the extending direction radially face other barrier parts, and the barrier parts adjacent to each other in the radial direction are positioned with an interval so that the fuel can flow to the suction cylinder part 53.
