Hydrogen tank body and method of producing the same, and hydrogen tank and method of producing the same

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.
