In a common rail for accumulating highly pressured fuel, a cylindrical body is provided with a chamber for accumulating highly pressured fuel and a delivery port which connects the chamber to the outer circumference thereof and communicates via a pipe-joining unit with a conduit in a distribution pipe. The longitudinal center axes of the chamber and the cylindrical body are disposed substantially coaxially with each other, and each of the longitudinal center axes of the delivery ports and the longitudinal center axis of the cylindrical body are skewed to each other. Accordingly, the durability of the cylindrical body is improved, and the thickness of the cylindrical body is uniform and the forging form of the cylindrical body becomes symmetric. The length of the delivery port is extended so that the durability of the cylindrical body is improved.
