Abstract

PURPOSE:To improve appearance and to simplify construction by a method wherein reflection surfaces are formed at least on the upper and lower surfaces of the inner surface of a cylindrical body. CONSTITUTION:The upper and lower surfaces of the inner surface of a cylindrical body 1 made of a steel sheet and formed in a square in cross section are formed by using a mirror. The opening on one end side of the cylindrical body 1 forms a slope pointing in an oblique upward direction. A metal mesh- containing glass sheet 12 are mounted on the slope to form a natural illumination unit A for a building. In construction of a building, a plurality of the natural illumination units A are juxtaposed on a living unit on the south side. When the interior of the cylindrical body 1 is exposed to sun light running through the slope of the natural illumination unit A, the sun light is fed to an opening part on the other end as reflection by a reflection surface being the inner upper and lower surfaces of the cylindrical body 1 is repeated.
