Abstract
A high-pressure tank fabrication method includes a pre-form fabrication step and a molding step. In the pre-form fabrication step a pre-form is fabricated by winding dry fiber bundles with different thicknesses (first fiber bundles and second fiber bundles) onto a liner in a state in which the dry fiber bundles with different thicknesses are made to be adjacent to one another. In the molding step, molding includes disposing the pre-form fabricated in the pre-form fabrication step in a mold and injecting resin.
