The present invention relates to a plastic sheet for holding information recording carriers, with which information recording carriers in the form of small disks, such as floppy disks, can be contained under control. In the holding sheet (1) according to the present invention, a pair of hanging members (8,8) for hanging the holding sheet (1) and large and small two types of index strips (7L,7S) are removably formed utilizing bottom plates (4a) of holding cavities (4) for holding information recording carriers. By mounting the index strips (7L,7S) in an insertion groove (3) formed on one side edge of the holding sheet (1), the wanted information recording carrier can be found easily. By mounting the pair of hanging members (8,8) by insertion into mounting holes formed in the vicinities of the both ends of the insertion groove (3), the holding sheet (1) can be hung in a cabinet or the like. Further, by forming a holding groove for holding non-used hanging members (8,8) in the backside of the holding sheet (1), loss of the hanging members can be prevented.
