PROBLEM TO BE SOLVED: To provide an RFID tag structure and a method of manufacturing it, capable of extending a communicable distance by positioning a high- permeability sheet-shaped magnetic material so that it extends to the outside of the antenna coil of an RFID tag from a magnetic flux formation area formed in the antenna coil, so that even if the RFID tag is mounted in proximity to a conductive member such as metal, the attenuation of magnetic flux by the conductive member is greatly reduced. SOLUTION: A first sheet material 6 on which a plurality of RFID tags 1a are aligned and fixed and a second sheet material 7 on which a plurality of sheets 5 of an amorphous magnetic substance are aligned and fixed are positioned and joined together in such a way that the sheets 5 extend to the outside of the antenna coil 2a of each RFID tag 1a from a magnetic flux formation area A formed in the antenna coil 2a. |
