PROCESS FOR MANUFACTURING IC CARD

摘要

A process for manufacturing an IC card includes a step of forming a plane coil by etching or punching a thin metal plate so that the plane coil consists of a conductor line wound as several loops in substantially the same plane and has respective terminals. A semiconductor element having electrodes is mounted on the plane coil. An adhesive agent or tape is attached to a predetermined area of the plane coil so that adjacent conductor lines in the loops are kept a predetermined gap therebetween. The plane coil is disposed between a pair of films to cover the plane coil therebetween, one of the films being provided with adhesive layer on a surface facing to the other film to seal the plane coil with the semiconductor element by attaching the pair of films with respect to each other by means of the adhesive layer.
