Abstract
A manufacturing method for a high-pressure tank includes joining a cylindrical member and dome members to each other so that a first reinforcing layer and a second reinforcing layer to which a cap is attached are formed, and after a resin material is poured inside the first reinforcing layer, rotating the first reinforcing layer so that the resin material covers an inner surface of the first reinforcing layer, and solidifying the resin material so that the liner is formed. The cap is attached to the first reinforcing layer so that a recessed portion in which the resin material is collected is formed between the cap and the first reinforcing layer. After the first reinforcing layer is rotated, the resin material is solidified in a state where the cap side is positioned on a lower side.
