IC card, antenna frame for IC card and method for manufacturing the same

摘要

An IC card includes an antenna formed as a flat coil wound several times having an inner vacant area, said antenna being made by punching or etching a thin metal strip and having an outermost loop partially connected to and supported by an outer frame of said thin metal strip, and said antenna having respective innermost and outermost terminals. A semiconductor element is electrically connected to said innermost and outermost terminals, respectively. One of said innermost and outermost terminals having an accommodation hole in which said semiconductor element is accommodated. The semiconductor element and the antenna are supported to maintain their form by a supporting material made of biodegradable resin.
