Abstract
A highly reliable inexpensive RFID medium (Radio-frequency Identification medium) and a method of manufacturing the same is provided, particularly for small, thin RFID mediums.A RFID medium includes a transmitting/receiving antenna 2 and an IC chip 3. A rectangular part of a base sheet 1, having a major surface on which transmitting/receiving antennas 2 are formed, is folded along one of the long sides thereof, and the other three sides are bonded to the base sheet 1 so as to cover the transmitting/receiving antenna 2 and the IC chip 3 connected to the transmitting/receiving antenna 2. The base sheet 1 has spacing parts of a predetermined shape for covering the transmitting/receiving antenna 2 and the IC chip 3 connected to the transmitting/receiving antenna 2. The transmitting/receiving antennas 2 and the spacing parts 22 are arranged alternately. The base sheet 1 is rolled in a roll.
