PURPOSE:To completely prevent production of a film or burrs on the part, opened to a fuel chamber, of a fuel injection valve mounting hole during injection molding of a fuel distributing pipe made of a synthetic resin material. CONSTITUTION:In a fuel distributing pipe 1, a fuel chamber F is formed therein along a longitudinal axis and a plurality of fuel injection valve mounting holes 2 each having the one end opened to the fuel chamber F and supporting a fuel injection valve are opened along a longitudinal axis. The fuel distributing pipe 2 is injection-molded by using a synthetic resin material. An injection gate passage opened to the fuel distribution pipe 1 is located on a line segment running the center of the cross section of each of a plurality of the fuel injection valve mounting hole 2, opened to the fuel chamber F, of the fuel distributing pipe 1 and positioned on the line segment extending along the longitudinal axis of the fuel distributing pipe 1 and on the side, situated facing the fuel injection valve mounting hole 2 opened to the fuel chamber F, of the fuel distributing pipe 1 and at the outside of the fuel distributing pipe 1. |
