Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent fuel leakage from a fuel injection valve by keeping a fuel supply line in a state of conduction regardless of variation of ambient temperature, after stop of an internal combustion engine, until restart of the engine after vapor lock does not occur in a fuel supply line. SOLUTION: In a fuel supply device, a one-way valve 11 for preventing fuel back flow when the upstream side of the fuel supply line L has lower pressure than the downstream side is disposed in the fuel supply line L for connecting a fuel pump 7 in a fuel tank T to the fuel injection valve 2 of the internal combustion engine E. A valve member 19 of the one-way valve 11 is connected to an opening spring 22 for opening the valve member 19 when pressure difference before and after the one-way valve 11 becomes substantial zero.
