Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress stress concentration due to the occurrence of a surface sink when an inner shell is resin-molded.SOLUTION: The pressure vessel 1 includes: an inner shell 3 formed of a resin molding; an outer shell 5 that covers the outer periphery of the inner shell 3, is made of FRP, and becomes a reinforcing layer; a cap 11 located at the axial end. The cap 11 has an inner cap component 7 and an outer cap component 9. The inner cap component 7 is integrally molded when the inner shell 3 is blow-molded. The inner cap component 7 includes a small diameter part 7c1 and a large diameter part 7c2, while the inner shell 3 includes a cylindrical neck 3a. The neck 3a is located at the outer peripheral part of the small diameter part 7c1. The axial end 3a2 of the neck 3a is in contact with the end surface 7e of the large diameter part 7c2.
