A hollow structure body capable of balancing weight reduction and excellent strength, the hollow structure constituted by a fiber-reinforced resin material, is provided. The hollow structure body has a hollow structure, in which a first shaped product constituted by a first fiber-reinforced resin material containing first reinforcing fibers and a first matrix resin and a second shaped product constituted by a second fiber-reinforced resin material containing second reinforcing fibers and a second matrix resin are combined, wherein in an arbitrary cross section in a direction perpendicular to an axial direction of the hollow structure, a ratio Sc/ St between compressive strength Sc of a structure in the first shaped product and tensile strength St of a structure in the second shaped product satisfies formula (1): Ãc / Ãt * Hc / Ht < Sc / St < Ãt / Ãc * Hc / Ht
