A card case accommodates a card or the like in a hollow portion formed as a result of attachment of a cover member to a bottom member. The cover member has such a structure as to allow reversal of its opposite sides in its attachment to the bottom member. Reversal of the opposite sides of the cover member changes the depth of a planar recess portion of the cover member, the planar recess portion partially constituting the hollow portion. Accordingly, the card case can cope with encapsulation of cards of different thicknesses.
