HIGH-PRESSURE TANK AND METHOD FOR MANUFACTURING HIGH-PRESSURE TANK

A method for manufacturing a high-pressure tank (10) including a liner (11) and a fiber-reinforced resin layer (12), the fiber-reinforced resin layer (12) having a first reinforcing layer covering an outer surface of the liner (11) and a second reinforcing layer (13) covering an outer surface of the first reinforcing layer includes: forming a cylinder member (21) made of a fiber-reinforced resin and having fibers oriented in a circumferential direction of the cylinder member (21); forming two dome members (22, 23) made of the fiber-reinforced resin; forming a reinforcing body (20) that is the first reinforcing layer by joining the cylinder member (21) and the dome members (22, 23); and forming on an outer surface of the reinforcing body (20) the second reinforcing layer (13) made of the fiber-reinforced resin and having fibers oriented across the dome members (22, 23).
