In order to solve this problem, the present invention particularly relates to a fuel supply device for a fuel injection valve inserted into a cylinder head 1 of an internal combustion engine, in which a pipe piece 13 penetrating the through part 11 of the cylinder head 1 is provided. The pipe piece 13 has a high pressure connecting portion 47 at an end of the supply side of the high pressure hole 15, and is provided on the valve holding support 5 of the fuel injection valve on the sealing surface 14 on the outflow side. In the form of being fixed firmly in the axial direction with respect to the conical seat surface 9 of the supply portion, the pipe piece 13 is connected to the conical seat surface 9 of the valve holding support 5 using a fixing flange. It is fixed firmly in the axial direction with respect to.
