PROBLEM TO BE SOLVED: To provide an FRP-made pressure vessel which has a composition that meets a sufficient maximum filling pressure and a minimum burst pressure and, does not cause a burst in the dome section, but instead causes in the cylinder section during braiding composition of a pressure vessel using reinforcing fiber. SOLUTION: The pressure vessel, which comprises a resin liner which is provided with dome sections on both sides of the cylinder section and a reinforcing fiber layer which covers the outside of the liner, has the reinforcing fiber layer formed by continuously making on the outer circumference of the cylinder and dome sections a braiding composition of the axial directional fiber composed at a braiding angle of 0 degree and the circumferential directional fiber composed at a given braiding angle which both are reinforcing fiber, and also composition which has the strength ratio of the axial directional fiber to the circumferential directional fiber at 3:1.
