Non-contact type IC card, antenna and antenna frame for IC card

An antenna for non-contact type IC card, said antenna comprising:

• a plane coil formed by punching or etching a thin metal plate in such a manner that a conductor line is wound several times on substantially the same surface, said metal plane coil including an antenna frame member whereby said metal plane coil is connected to said metal frame member by supporting sections, said supporting sections being cut-off therefrom, said plane coil having respective terminals at innermost and outermost ends, and having an accommodation hole, said innermost end terminal being provided with accommodation terminals and arranged in said accommodation hole;
• a semiconductor element having electrode terminals and arranged in said accommodation hole;
• a circuit film comprising an insulating resin film and a circuit pattern formed on said insulating resin film, said circuit pattern electrically connecting said electrode terminals of the semiconductor element to said terminals of the plane coil;
• and
• at least one projection integrally formed with said conductor and extending therefrom inwardly or outwardly so as not to contact with an adjacent loop of said conductor line, said projection being located at any desired position to be used as a suction pad, an alignment mark or a positioning guide when said plane coil is sucked or positioned.
