<p><P>PROBLEM TO BE SOLVED: To provide a conductive sheet for a non-contact IC card with a built-in antenna whose electric connectivity is highly reliable, whose circuit pattern formation is satisfactory, and whose producing efficiency is satisfactory. <P>SOLUTION: This conductive sheet for a non-contact IC card with a built-in antenna is constituted by forming conductive layers on both faces of an insulating substrate, and electrically connecting the conductive layers on both faces through a through-hole or via-hole opened so as to be put through the insulating substrate. The conductive layers are directly formed on the insulating substrate, and configured in the same way on the wall face of the through-hole or the inside of the via-hole and on both faces of the insulating substrate, and the conductive layers constitutes a circuit including an antenna. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
