<P>PROBLEM TO BE SOLVED: To manufacture an optical disk on which a non-contact type IC chip is mounted in a simple process at low cost. <P>SOLUTION: A spiral antenna coil 4 is formed by blanking or cutting work from a metal plate and both end parts of the antenna coil 4 and respective electrodes of an IC chip module 3 on which the non-contact type IC chip 2 is mounted are electrically connected. An optical disk substrate 1 provided with a recessed part is molded and the antenna coil 4 to which the IC chip module 3 is connected is disposed and enclosed in the recessed part of the optical disk substrate 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
