Abstract
An IC card, which can be mass-produced at low cost, is composed of a plane coil formed by means of punching or etching. The plane coil in which a conductor line is wound a plurality of times in substantially the same plane is formed by punching, terminals of the plane coil and electrode terminals of the semiconductor element are electrically connected to each other, the plane coil is provided with an outside terminal formed outside the coil and an inside terminal formed inside the coil, the semiconductor element is arranged in such a manner that a forming face on which the electrode terminals are formed or a plane reverse to the forming face is opposed to the conductor line of the plane coil the electrode terminals of the semiconductor element are respectively located adjacent to the outside terminal and the inside terminal of the plane coil and the electrode terminals are electrically connected to the terminals of the plane coil located on the same side with respect to the inside and outside of the coil.
