A high-durability storage case is provided in which a disc can be smoothly inserted into and taken out from the storage case, and in which attachment and detachment operations of the disc can be stably performed. According to the storage case ( 2 ), a case body ( 3 ), a case cover ( 4 ), and a supporting plate ( 5 ) supporting a disc ( 1 ) are pivotally supported in a mutually openable/closeable manner by a four-link mechanism ( 16 ) defined by first, second, third, and fourth hinges ( 11 ), ( 12 ), ( 14 ), ( 15 ) and an arm segment ( 13 ). When the case cover ( 4 ) is opened or closed with respect to the case body ( 3 ), the supporting plate ( 5 ) is drawn into or drawn away from the case body ( 3 ) together with the case cover ( 4 ).
