Abstract
A high-pressure tank includes: a liner including a body portion having a tubular shape and side end portions each having a dome shape, the side end portions being provided on opposite sides of the body portion; and a reinforcement layer made of fiber reinforced resin covering an outer surface of the liner. The reinforcement layer includes a tubular member covering the body portion and dome members joined to opposite sides of the tubular member so as to cover the side end portions. The liner includes a first resin layer defining a storage space for storing gas and a second resin layer provided between the first resin layer and at least the tubular member. An elastic modulus of a second resin constituting the second resin layer is lower than an elastic modulus of a first resin constituting the first resin layer.
