Abstract
Provided is a pressure-resistant container that allows a time required for winding a fiber-reinforced member on both a tubular barrel portion and dome portions of a container body to be shortened. A pressure-resistant container includes: a container body having a tubular barrel portion, and dome portions that are provided integrally on both end portions, respectively, in an axial direction, of the tubular barrel portion; and a fiber-reinforced member that covers an outer surface of the container body. The fiber-reinforced member includes a first fiber sheet that is formed from fibers oriented in one direction, and that has a fiber direction in which the fibers extend such that the fiber direction is tilted relative to the axial direction of the container body at such an angle as to cover both the dome portions, on both sides in the axial direction, of the container body. The first fiber sheet has a sheet body portion formed in a sheet-like shape, and a plurality of protruding portions that are aligned on and protrude from both end portions, in a fiber direction, of the sheet body portion. The sheet body portion is wound along an outer surface of the tubular barrel portion to cover …
