Method for manufacturing a non-contact type IC card
A non-contact type IC card includes a plane coil comprising a conductor line wound several times on substantially the same surface. The plane coil has respective terminals at the innermost and outermost ends. A semiconductor element has electrode terminals electrically connected to the terminals of the plane coil, respectively. A resin-filled portion is defined by a part of the circumference of the plane coil where spaces between adjacent loops of conductor line of the plane coil are filled with light-setting resin to maintain predetermined intervals between the adjacent conductors lines of the plane coil.
