Abstract
Provided is a pressure vessel comprising a liner and an insert member that are integrally formed by blow molding the liner. The insert member has a cylindrical shape with an inner diameter opening portion. The liner is molded integrally with the insert member by inserting a parison through the inner diameter opening portion and performing blow molding. Since the liner is inserted inside the insert member and is blow molded, a pinched portion is not generated. Consequently, strength of the pressure vessel can be improved, and fluid is prevented from leaking between the liner and the insert member.
