Abstract
A high pressure tank includes: a liner having a space in which a gas is sealed; and a reinforcement layer configured to cover a periphery of the liner. The liner has a cylinder portion in a cylindrical shape, and a pair of dome portions provided at both ends of the cylinder portion in an axial direction of the cylinder portion. A curved surface shape of each dome portion is an equally stressed curved surface shape when an internal pressure of the liner reaches a setting pressure set higher than the atmospheric pressure.
