Zusammenfassung:	To detect the presence/absence of a fault in a gas barrier layer.SOLUTION: A pressure container A includes: a liner 10 having a multilayer structure made of a synthetic resin; and a barrier layer 20 that is made of a synthetic resin to which an ultraviolet light emitter that emits light when irradiated with ultraviolet ray is added, and that constitutes the liner 10. In a case where there is a fault portion in the barrier layer 20, when the liner 10 is irradiated with ultraviolet ray, only the fault portion does not emit light, and thus based on the presence or absence of a portion that does not emit light, it is possible to detect whether or not there is a fault portion in the barrier layer 20.SELECTED DRAWING: Figure 2 【課題】ガスバリア層における層切れの有無を検出する。【解決手段】圧力容器Ａは、合成樹脂からなる多層構造のライナー１０と、紫外線の照射により発光する紫外線発光体が添加された合成樹脂からなり、ライナー１０を構成するバリア層２０とを備えている。バリア層２０に層切れ部位が存在している場合、ライナー１０に紫外線を照射したときに、その層切れ部位だけが発光しないので、発光しない部位の有無に基づいて、バリア層２０に層切れ部位が存在するか否かを検出することができる。【選択図】図２
