Ic tag and method for production thereof

摘要

An IC tag includes a plane coil (20) which is made by a conductor wire (18) coated with an insulator wound several times in a plane, the plane coil (20) having terminal portions and defining a central vacant area encircled by the wound wires. A semiconductor element (14) is arranged in the central vacant area and placed in the plane and has a thickness substantially the same as or smaller than the thickness of the plane coil (20). The semiconductor element (14) has electrodes which are electrically connected to the terminal portions of the plane coil (20). <IMAGE> <IMAGE>
