High-pressure storage tank

The invention provides a high-pressure storage tank. A high-pressure tank (10) is provided with: a resin liner (12) having a cylindrical cylinder section (22); a first end cap member (161) connected to a first connection end portion (24a) of the cylinder portion (22); a second end cap member (162) connected to a second connection end portion (24b) of the cylinder portion (22); and a reinforcing layer (14) having first reinforcing fibers (261) wound so as to be wound in a circumferential direction along the circumferential direction of the cylinder section (22). The reinforcing member (18) is bridged between the first end cap member (161) and the second end cap member (162). The reinforcing member (18) has second reinforcing fibers (381) that are wound a plurality of times in the circumferential direction on the first end cap member (161) and the second end cap member (162). Therefore, the use amount of the reinforcing fibers can be reduced, the manufacturing cost and the weight of the high-pressure storage ta
