Provided is a method for manufacturing a high-pressure tank with an improved bonding force between a first reinforcement layer and a second reinforcement layer. A tank unit (1) includes a high-pressure tank (10), and a connection member (30) connected to the high-pressure tank (10). The connection member (30) includes ring-shaped seal members (61, 62) disposed between a liner (11) and an insertion unit (31), and sealing a housing space (S). The high-pressure tank (10) includes a cylindrical body (40A) disposed on a position opposed to the seal members (61, 62), and limiting deformation expanded in a diameter direction of the inner circumference surface of a neck unit (15), so as to orbit the outer circumference surface (11a) of the liner (11), with respect to a space between the liner (11) and a reinforcement layer (12). The Young's modulus of a material along a circumferential direction of the cylindrical body (40A) is higher than the Young's modulus of a material along a circumference direction of the liner (11) and the Young's modulus of a material along a circumferential direction of the reinforcement layer (12).

    제1 보강층과 제2 보강층의 접착력이 향상된 고압 탱크의 제조 방법을 제공한다. 고압 탱크(10)와, 고압 탱크(10)에 접속되는 접속 부재(30)를 구비한 탱크 유닛(1)이다. 접속 부재(30)는, 라이너(11)와 삽입부(31) 사이에 배치되고, 수용 공간 S를 밀봉하는 환 형상의 시일 부재(61, 62)를 구비하고 있다. 고압 탱크(10)는, 라이너(11)와 보강층(12) 사이에 있어서, 라이너(11)의 외주면(11a)을 주회하도록, 시일 부재(61, 62)에 대향한 위치에 배치되고, 네크부(15)의 내주면의 직경 방향으로 확대되는 변형을 제한하는 통 형상체(40A)를 구비하고 있다. 통 형상체(40A)의 둘레 방향을 따른 재료의 세로 탄성률은, 라이너(11)의 둘레 방향을 따른 재료의 세로 탄성률 및 보강층(12)의 둘레 방향을 따른 재료의 세로 탄성률보다도 높다.
