Abstract
An information carrier in which an IC element formed integrally with a coil is mounted and which has an extended communication range and a method of manufacturing the same and a structure of the IC element appropriately suited for this sort of information carrier and a method of manufacturing the same. In the IC element, a conductor constituting the coilis implemented in a multilayer structure including a metal-sputtered layer or alternatively a metal-evaporated layerand a metal-plated layer. In the method of manufacturing the IC element, a precision electroforming method is employed as a means for forming the metal-plated layer. The information carrier is implemented in such a structure in which the IC elementis disposed at a center portion in a planar direction of a substrate. In a method of manufacturing the information carrier, strip material or materialstoa given one of which has mounted thereon desired parts inclusive of the IC elements are manufactured, whereon desired information carriersare formed by punching the strip material(s).
