PROBLEM TO BE SOLVED: To provide a pressure container and a method of manufacturing the same such that a reinforcement layer having reinforcement fiber crossed can be easily formed on a surface.SOLUTION: A pressure container is provided with a metallic liner 11 in a hollow doughnut shape; a first reinforcement layer 12 which covers the outside of the liner 11 by curing a prepreg 31 along a peripheral direction B of the liner 11 with resin; and a second reinforcement layer 13 which covers the outside of the liner 11 (first reinforcement layer 12) as a plurality of pre-cured members 43a and 43b, and 45a and 45b by curing a carbon fiber tow 42 along the axial direction A of the liner 11 with resin. 【課題】圧力容器及びその製造方法において、表面に強化繊維が交差してなる強化層を容易に形成可能とする。【解決手段】中空ドーナツ形状をなす金属製のライナ１１と、このライナ１１の周方向Ｂに沿うプリプレグ３１が樹脂により硬化されてライナ１１の外側を被覆する第１強化層１２と、このライナ１１の軸方向Ａに沿う炭素繊維トウ４２が樹脂により硬化された複数のプリキュア部材４３ａ，４３ｂ，４５ａ，４５ｂとしてライナ１１（第１強化層１２）の外側を被覆する第２強化層１３とを設ける。【選択図】図１
