Abstract
A manufacturing method for a high-pressure tank is a manufacturing method for a high-pressure tank including a reinforced layer formed such that an electrically conductive fiber bundle impregnated with thermosetting resin is wound around a liner. The manufacturing method includes: a step of preparing the tank in which the uncured reinforced layer is formed on the liner; a first heating step of heating the uncured reinforced layer by low-frequency induction heating so the thermosetting resin is softened; and a second heating step of, after the first heating step, heating the softened reinforced layer by high-frequency induction heating so that the softened reinforced layer is hardened.
