Abstract
This high-pressure tank includes a resin liner constituting a hollow fluid filling part, a ferrule including a supply/discharge port which communicates with an internal space of the liner and a flange part which protrudes outward in a radial direction from a circumferential region of the supply/discharge port and abuts on the liner, and a reinforcing layer made of a fiber reinforced resin attached to cover across the liner and an outer circumferential surface of the flange part, in which a discharge hole allowing a gap between abutting surfaces of the flange part and the liner to communicate with an inside of the supply/discharge port and discharging a fluid accumulated between the liner and the reinforcing layer to the supply/discharge port is provided in the ferrule, and a trap groove surrounding a circumferential region of the discharge hole is provided on at least any one of the abutting surface on the flange part side and the abutting surface on the liner side.
