Abstract:
A process of manufacturing an IC card comprising the following steps of:forming a plane coil by etching or punching a metal plate so that said plane coil consists of a conductor line wound as several loops in a substantially same plane and has respective terminals; mounting a semiconductor element on said plane coil, and attaching an adhesive tape to a predetermined area of said plane coil so that adjacent conductor lines in the loops have a predetermined gap therebetween; disposing said plane coil between a pair of films to cover said plane coil therebetween, at least one of said films being provided with adhesive layer on a surface facing to the other film to seal said plane coil with said semiconductor element by attaching said pair of films with respect to each other by means of said adhesive layer; forming an IC card frame by etching or punching a metal plate so that said IC card frame comprises at least one plane coil consisting of a conductor line wound as several loops in substantially the same plane and having respective terminals and a frame connected to and spaced by a predetermined distance from said plane coil so as to support said plane coil; and separating said at least on plane coil from said frame; forming an IC card frame comprising at least one plane coil, at least one inner frame portion and an outer frame portion, said inner and outer frame portions being located inside and outside of said at least one plane soil and connected to and spaced by predetermined distances from innermost and outermost conductor lines of the plane coil so as to support said plane coil; and separating said at least one plane coil from said inner and outer frame portions.
