The CD storage box is integrally formed and has a plurality of mutually neighboring recesses in a recessed surface thereof, which recesses have their heights lowered from the first one gradually to the last one. Each recess has an annular chamber in corresponding by size to the diameter of a CD; the annular chambers each has a bottom surface with a predetermined radial width and an inner wall perpendicular to the bottom surface, and each is provided with a CD positioning means; each recess has a height different from those of its neighboring ones, part of their peripheries are mutually overlapped with a neighboring one as if the peripheries have notches. Thereby the present invention can be used to more firmly position more CD's under the condition of being given with a CD storage box having an identical volume to a conventional one.
