Provided is a method for manufacturing a high-pressure tank in which the adhesive force between a first reinforcing layer and a second reinforcing layer is improved. A tank unit (1) is provided with a high-pressure tank (10) and a connection member (30) connected to the high-pressure tank. The connection member (30) is provided with annular seal members (61, 62) that are disposed between the liner (11) and the insertion section (31) and that close the accommodation space (S). The high-pressure tank is provided with a cylindrical body (40A) which is disposed between the liner (11) and the reinforcing layer (12), is disposed at a position facing the seal members (61, 62) so as to surround the outer peripheral surface (11a) of the liner (11), and restricts deformation of the inner peripheral surface of the neck (15) that expands in the radial direction. The longitudinal elastic modulus of the material in the circumferential direction of the cylindrical body (40A) is higher than the longitudinal elastic modulus of the material in the circumferential direction of the liner and the longitudinal elastic modulus of the material in the circumferential direction of the reinforcing layer.

    本发明提供第1加强层与第2加强层的粘合力提高的高压罐的制造方法。是具备高压罐(10)、和与高压罐连接的连接部件(30)的罐单元(1)。连接部件(30)具备配置于衬里(11)与插入部(31)之间并将容纳空间(S)封闭的环状的密封部件(61、62)。高压罐具备筒状体(40A),该筒状体(40A)配置在衬里(11)与加强层(12)之间,以环绕衬里(11)的外周面(11a)的方式配置于与密封部件(61、62)对置的位置,并限制颈部(15)的内周面的在径向上扩展的变形。筒状体(40A)的沿着周向的材料的纵向弹性模量高于衬里的沿着周向的材料的纵向弹性模量和加强层的沿着周向的材料的纵向弹性模量。
