The pressure vessel includes: a liner (2) having a hollow portion; and a reinforcing layer (4) that covers the circumference of the liner (2). The reinforcing layer (4) is formed by binding bands (11) composed of reinforced fibers around the liner (2) so as to be layered, a lap portion (21, 22) is formed with ends of the adjacent bands (11, 11) superposed one on another in each layer of the reinforcing layer (4); and at least one end of the adjacent bands (11, 11) in the lap portion (21, 22) is formed thinner than any other portion of the band (11).
