Abstract
A high-pressure tank includes a first reinforcing layer and a second reinforcing layer. The first reinforcing layer is a layer obtained by joining dome members to respective end portions of a cylinder member, the dome members being a pair, and an inner peripheral surface of the cylinder member is exposed to a storage space that stores gas. A first resin layer covers the cylinder member between the first reinforcing layer and the second reinforcing layer. The first resin layer is less permeable to the gas in a thickness direction than the first reinforcing layer.
