The fiber reinforced composite material layer 96 is formed by winding a resin impregnated fiber impregnated with a thermosetting resin around a resin liner 94 by a filament winding method. The resin-impregnated fiber is wound around the resin liner 94 under a predetermined tension.

  Since the resin contained in the resin-impregnated fiber bundle is an uncured resin, it has low resin viscosity and fluidity. Therefore, the resin contained in the resin-impregnated fiber bundle wound inside on the resin liner 94 side is directed outwardly on the glass fiber layer 98 side due to a winding effect when the resin-impregnated fiber bundle is wound around the resin liner 94. May flow. In such a case, in the fiber reinforced composite material layer 96 formed by curing a laminate in which the resin-impregnated fiber bundles are laminated, the resin volume content is further reduced due to the outflow of the resin on the resin liner 94 side. The fiber volume content may be higher. On the contrary, on the glass fiber layer 98 side, the resin volume content is higher, and the fiber volume content may be further reduced. In the case of the high-pressure tank 90, a larger stress is applied to the fiber reinforced composite material layer 96 on the resin liner 94 side. Therefore, if the fiber volume content on the resin liner 94 side in the fiber reinforced composite material layer 96 is increased, fatigue durability and the like may be reduced.
