| description | To provide a manufacturing method of a high-pressure tank capable of preventing local increase of a diameter of a tank at an end portion of a cylindrical portion.SOLUTION: A manufacturing method of a high-pressure tank including a liner having a cylindrical portion and dome portions formed at both ends of the cylindrical portion, and a reinforcement layer formed at an outer side of the liner by a filament winding method: has a high angle helical winding layer formation process for forming a high angle helical winding layer by multiply winding fibers on the liner by high angle helical winding with an angle in which a winding angle to an axis of the high pressure tank is within a predetermined range. In the high angle helical winding layer formation process, a ratio of an axial length of a region where a winding angle of the high angle helical winding to an axis of the high-pressure tank is changed, to a maximum value of folding-back frequency of the high angle helical winding is 2 to 4 in folding-back of the high angle helical winding at the end portion of the cylindrical portion.SELECTED DRAWING: Figure 4
