The purpose of the present invention is to provide a fuel rail in which an intersection hole section has increased strength and which is lightweight. This fuel rail for an internal combustion engine is provided with: a fuel rail body 1 which has a circular cylindrical shape; and injector mounting sections 2 which have formed therein fuel supply holes 2d connecting to injectors and to which the injectors are mounted. The injector mounting sections 2 are formed integrally with the fuel rail body 1 so that the fuel supply holes 2d intersect the center hole 1a of the fuel rail body 1, and the injector mounting sections 2 are arranged in the longitudinal direction of the fuel rail body 1. The wall thickness of the roots of the injector mounting sections 2 is set to be larger than the wall thickness of the portion of the fuel rail body 1, which is located between adjacent injector mounting sections 2. |
