Abstract: In a method for manufacturing a high-pressure tank, a fiber bundle impregnated with a thermosetting resin base material is wound around an outer surface of a liner in a state where tension is applied to the fiber bundle in a filament winding step. The filament winding step includes a pressure-bonding step and a cutting step. In the pressure-bonding step, a terminal end portion which is a winding end of the fiber bundle is thermocompression-bonded to an outer peripheral portion of the fiber bundle wound around the liner. In the cutting step, a surplus portion of the fiber bundle is cut by a cutting tool.
