A fiber-reinforced resin hollow body includes an axial-direction fiber layer containing reinforcing fibers aligned parallel to an axial direction of the hollow body, and a non-axial-direction fiber layer provided on top of at least one of an internal and an external side of the axial-direction fiber layer, and containing reinforcing fibers oriented in a direction different from the alignment direction of the axial-direction fiber layer. The non-axial-direction fiber layer includes one or more peripheral-direction fiber layers containing reinforcing fibers aligned parallel to a peripheral direction of the hollow body, and one or more non-aligned fiber layers containing reinforcing fibers not aligned in a specific direction.

A fiber-reinforced resin hollow body includes an axial-direction fiber layer containing reinforcing fibers aligned parallel to an axial direction of the hollow body, and a non-axial-direction fiber layer provided on top of at least one of an internal and an external side of the axial-direction fiber layer, and containing reinforcing fibers oriented in a direction different from a direction in which the reinforcing fibers contained in the axial-direction fiber layer are aligned. The non-axial-direction fiber layer has end portions in a peripheral direction of the hollow body, the end portions overlapping each other.
