PROBLEM TO BE SOLVED: To provide a fuel supply device capable of executing appropriate fuel injection in response to an operating condition of an internal combustion engine in a direct-injection type internal combustion engine. SOLUTION: A fuel array means 18 comprises a fuel array apparatus 30 of a cylinder with sealed top and bottom and a plurality of flow passages having opening/closing valves communicating with the fuel array apparatus 30. In the top of the fuel array apparatus 30, a flow passage 32 for fuel to be used which is connected to a fuel pump 14 is opened. A specific component flow passage 34 and a separated residual content flow passage 36 connected to a fuel content separator 16 face a side of the fuel array apparatus 30. An array fuel passage 38 connected to an injector 20 communicates to the bottom of the apparatus 30. Control valves 31, 33, 35 (hereafter also called opening/closing valves) such as a solenoid valve are respectively arranged in the flow passage 32 for fuel to be used, the specific component flow passage 34 and the separated residual component flow passage 36, and opened/closed through an opening/closing valve drive circuit 15 by a command of the ECU 13.
