In order to constitute a fuel high-pressure pipe that is compact and easy to connect to injectors, one of both the end sections of a fuel high-pressure pipe is formed as a first connecting section connected to a fuel supply port of one injector, and the other one of the end sections of the fuel high-pressure pipe is formed as a second connecting section connected to a fuel discharge port of another injector. The first connecting section and the second connecting section are linearly formed parallel to each other, and head sections of the first connecting section and the second connecting section, said head sections being on the connecting side to respective injectors, are formed in the directions opposite to each other.
