Abstract
A high pressure tank includes: a resin liner for containing a fluid; a reinforced layer covering an outer surface of the liner; and a cap including a supply/discharge hole for supplying and discharging the fluid to and from the liner. Gas vent passages formed in the cap each including at one end a first opening open toward the cap-facing surface of the liner and at the other end a second opening open toward at least one of an inside of the supply/discharge hole and an outside of the reinforced layer. A cross-sectional area of the gas vent passage at the one end perpendicular to a longitudinal direction and the first opening are smaller than other cross-sectional areas of the gas vent passage perpendicular to the longitudinal direction.
