The holder tray for compact disc of the invention has a disc-engagement structure capable of holding a disc mounted thereon very reliably still with little resistance against demounting of the disc therefrom. The disc-engagement structure has a center pushing part raised above the center opening and connected with a plurality of radially arranged connecting pieces each in a cranked confuguration connecting the central pushing part and the periphery of the center opening, the riser parts collectively forming a cylindrical surface to contact with the inner periphery of the center hole of a compact disc mounted thereon. Further, a plurality of radially arranged flap pieces extend from the center pushing part each in a cantilever-like manner and each between two connecting pieces and, when the pushing part is pushed down, the free ends of the flap pieces are raised so as to push up the disc facilitating demounting thereof.
