This invention has for its object to provide a coin-shaped IC tag which can be endowed with a predetermined weight, thereby to ensure a normal operation and to afford a satisfactory feeling of weightiness as a value medium, and a Method of manufacturing the coin-shaped IC tag . This invention is characterized by a coin-shaped IC tag Comprising an IC packaging base member in which an electronic circuit for communicating data and for recording data is mounted on a base material; a high specific gravity resin material whose specific gravity is increased by mixing a material of high specific gravity into a resin material, and which is foraed into a flat shape ; an IC tag core which is formed by joining the high specific gravity resin material in the flat shape and the IC packaging base member, and a covering which is formed of a resin material at, at least, an outer peripheral edge of a surface of said IC tag core so as to present a coin shape. <IMAGE> |
