To provide a small fuel rail capable of reducing a temperature difference of a fuel supplied to a combustion chamber of an internal combustion engine which occurs between cylinders.

Multiple combustion chambers 40 are formed at the inner side of a cylindrical rail body 20 so as to correspond to multiple fuel jet valves 10. Each of the combustion chambers 40 includes: a fuel inflow port 41 where a fuel from a fuel tank 6 flows in; and a fuel outflow port 42 where the fuel flows out toward the fuel jet valve 10. A heating part 52 is provided at each combustion chamber 40 and may heat the fuel in the combustion chamber 40.
