    Abstract: PROBLEM TO BE SOLVED: To provide a smaller and lighter fuel supply device with a less number of parts. SOLUTION: A supporting member 20 for supporting a fuel pump 31 is formed of a resin integrally with a flange 11 for closing an opening portion of a fuel tank. Thus, the number of parts and the size of a constitution are reduced without requiring a separate member for connecting the supporting member 20 to the flange 11 and a site where the separate member is installed. The supporting member 20 is located radially inside of the flange 11. Thus, no under-cut portion is formed. This allows easy parting of a mold when integrally molding the flange 11 and the supporting member 20. As a result, no parting line due to the parting is formed on the flange 11, preventing the formation of a level difference between the flange 11 and the fuel tank and improving sealing performance between the flange 11 and the fuel tank.
