To provide a metallic cylindrical body suited for use as a component excellent in the wear resistance of its inner peripheral wall and subject to sliding friction, such as a cylinder liner for an internal combustion engine, and also to provide a method of manufacturing the metallic cylindrical body whereby a thin cylindrical body is manufactured accurately at low cost and with good productivity.

The metallic cylindrical body is made of an aluminum alloy containing 13 to 18 mass% Si, with primary-phase Si crystallized more densely on the inner peripheral wall than on the outer peripheral wall of the cylindrical body. The method of manufacturing the metallic cylindrical body 20 includes: pouring a molten metal into a rotor 12 positioned within a cylindrical mold 11; scattering the molten metal using the rotation of the rotor 12; and accumulating the scattered molten metal on the inner peripheral wall of the mold 11.
