Abstract: A hydrogen tank body includes a base layer formed of a synthetic resin selected from the group consisting of silicon resin, polyphenylene sulfide, polybutylene terephthalate, polyvinyl chloride, polypropylene, polyethylene, and polycarbonate, and a liner layer formed of hydrogen impermeable resin, on an inside wall surface of the base layer.

Abstract: A method of manufacturing a gas tank comprises: a step (a) of preparing a liner having a hollow cylindrical shape; a step (b) of forming a first layer by winding a first fiber bundle impregnated with resin around the liner; a step (c) of forming a second layer by winding a second fiber bundle impregnated with resin around the liner with the wound first fiber bundle in such a manner that portions of the second fiber bundle overlap each other in a direction parallel to a center axis of the liner; a step (d) of causing a section where the portions of the second fiber bundle overlap each other to get into the first layer; and a step (e) of curing the resin.
