A pressure container manufacturing method by forming an outer shell of a
fiber reinforced
composite material on a periphery of a liner having a cylindrical portion, dome portions connected to both ends of the cylindrical portion, and a
mouth piece disposed on one top of the dome portions, has: forming a body on the periphery by braiding
fiber bundles provided from bobbins of a braider disposed in a circumferential direction of the liner, while moving the liner in an axial direction, wherein when body formation reaches a root portion of the
mouth piece, a movement in a first direction of the liner is stopped, each
bobbin is rotated approximately a half-turn in the circumferential direction, and thereafter formation of the body is continued while moving the liner in a second direction opposite to the first direction; and curing a resin impregnated in the
fiber bundles, to form an outer shell.
