PROBLEM TO BE SOLVED: To provide a fuel supply method and a fuel supply mechanism to a fuel injection device having a plurality of fuel injection devices and fuel injection mechanisms performing combustion in stages. SOLUTION: The fuel injection device A comprising a holding supplying part 20 for holding a fuel injection part 10 and supplying the fuel and the combustion air to the fuel injection part, further comprises a first fuel injection member 30, a first atomizing mechanism 40 mounted on an outer periphery of the first fuel injection member 30, a second fuel injection member 50 mounted on an outer periphery of the first atomizing mechanism 40, a second atomizing mechanism 60 mounted on an outer periphery of a second fuel injection member 50, and an outer cylinder 70 mounted on an outer periphery of the second atomizing mechanism 60. The holding supplying part 20 has an integrated part 25 and a fuel feed arm 26 integrated without performing welding, and incorporates first fuel supply passages 27, 28 for supplying the fuel to the first fuel injection member 30 and second fuel supply passages 27, 28 for supplying the fuel to the second fuel injection member 50, to supply the fuel.
