Abstract
This manufacturing method is a manufacturing method of a high-pressure tank that is formed by joining dome-shaped side end members to both ends of a cylindrical tube member and that has a first reinforcing layer made of fiber-reinforced resin. The manufacturing method has a joining step of joining the side end members to both ends of the tube member such that an outer wall surface of the tube member and an inner wall surface of each side end member face each other. In the joining step, a margin for overlap between each side end member and the tube member in an axial direction of the tube member is within a range of 5% or more to 35% or less relative to the inside diameter of the tube member.
