High-pressure tank and manufacturing method of the same

A high-pressure tank, comprising:

• a liner that includes a body that is cylindrical in shape and a pair of dome portions each of which is provided at a respective end of the body in an axial direction;
• and
• a reinforcing layer provided on an outer circumferential face of the liner, wherein:
• the reinforcing layer includes
• a pair of resin members, each of which is provided encircling a respective end portion of an outer circumferential face of the body,
• a hoop layer that covers part of the outer circumferential face of the body, between the resin members, and
• a helical layer that covers the resin members, the hoop layer, and the dome portions;
• and wherein:
• the resin members are configured to cover part of the body from boundary portions between the body and the dome portions, and increase in thickness from the boundary portions toward a middle of the body,
• the thickness of the hoop layer is the same as the greatest thickness of the resin members, and
• the resin members are made of a different resin material from the hoop layer.
