Zusammenfassung:PROBLEM TO BE SOLVED: To provide a card case which is easy to operate, excellent in durability, and reduced in costs without causing any erroneous operation due to the interference of two non-contact IC cards. SOLUTION: When two non-contact IC card are stored, electronic shielding layers and electromagnetic absorbing layers are arranged so that the electromagnetic absorbing layers can exist at the both non-contact IC card sides, and that the electromagnetic shielding layers can exist on the back faces. The outer sides of the electromagnetic absorbing layer and the electromagnetic shielding layer are set to the same dimension, and set so as to be vertically and horizontally larger than the outer sides of the non-contact IC cards by 1-4 mm.
