Provided is a toroidal pressure vessel having extremely high pressure resistance. Laminating latitudinal reinforcing fiber layers (32) enables to improve a strength in a latitudinal direction of a pressure vessel (1). Moreover, putting reinforcing fibers (32a) constituting those laminated latitudinal reinforcing fiber layers (32) in continuity enables to further improve the strength in the latitudinal direction of the pressure vessel (1), for example compared with a case where the reinforcing fibers are divided for each layer.
