Abstract
An improved contactless integrated circuit (IC) card of the type having one or more laminate members, a wire-wound coil provided on the laminate member for receiving power and for transmitting and receiving signals to and from an external device, and an IC module for inputting and outputting the signals, the wire-wound coil being coupled to the IC module, wherein the improvement comprises an end portion of the wire-wound coil being formed into a buffer portion near the point at which the wire-wound coil is coupled to the IC module so as to absorb tension generated in the wire-wound coil.
