The present invention relates to a disc case 1 , which alternates conventional disc cases made of a plastic resin. The disc case 1 is capable of housing a disc body 100 having a periphery with a radius R 100 . The disc case 1 comprises a base layer 41 extending to a cover layer 43 via a crease 42 , the base layer 41 with the cover layer 43 being foldable in two at the crease 42 ; a first layer 11 provided above the base layer 41 , the first layer 11 having a first opening 12 formed in a circle corresponding to the periphery of the disc body; a second layer 21 provided on the first layer 11 , the second layer 21 having a second opening 22 formed in a partial circle in a size to pass the disc body, and covering a part of the first opening 12 ; and a third layer 31 provided between the base layer 41 and the first layer 11 , the third layer 31 having an third opening whose periphery supports the periphery of the disc body. The disc body is capable of inserted from the second opening 22 and fitted in the first opening 12 . The cover layer 43 is folded to cover the upper surface of the second layer 21.
