An RFID tag-incorporated game card having no irregularities on its surface layers is provided. In a card, an intermediate layer having an RFID tag incorporated therein with an appropriately uniform thickness is held between at least two sheets. The intermediate layer includes the RFID tag and at least two base films arranged to hold the RFID tag between them. The base films are preferably colored black. Alternatively, it is also preferable that the intermediate layer and the sheets are adhered to each other using a black adhesive.
