To provide a two-disk container which accommodates disks in its lid and body, thereby making a case body thinner, and prevents disengagement of disks accommodated in the container.

Disk accommodating sections are defined in both the body and lid of the case body which comprises the body and the lid. The centers of projections having small juts which are accommodated in the through-holes of disks in order to prevent disengagement of the disks are displaced with respect to each other, thereby preventing disengagement of the disks. One of the projections presses the other projection and the disk at the same time and, thus, disengagement of the disks are prevented. Further, by providing a cut face defined by cutting the bottom of each projection obliquely, the projection can be deeply pressed. Thus, the height of a support frame which supports the perimeter of each disk is reduced and the case body is made thinner.
