To solve the problem that a non-contact type recording medium is usually carried by storing it in a wallet or a card case by spread of an IC card, etc. in recent years, while, data recorded in the recording medium may be unauthorizedly acquired, destroyed and altered by a malicious third party.

Unauthorized acquisition, destroy and alteration of the data stored in the non-contact type recording medium by the third party is prevented by inserting paper including black body blended therein (Japanese patent application 2003-82597) with an electromagnetic wave shielding effect between two cloths of outer material and lining when the front part of the wallet and the card case, etc. is sewn. In addition, since it is the above-mentioned means, the electromagnetic wave shielding effect is obtained without requiring a special process in the case of manufacturing and without influencing appearance of an article as well.
