<P>PROBLEM TO BE SOLVED: To allow efficient communication, in a communication device, and a manufacturing device and method. <P>SOLUTION: On green sheets 101-3 to 101-10, capacitor patterns 103-1 to 103-8 and antenna patterns 104-1 to 104-8 are formed, respectively. When the green sheets 101-3 to 101-10 are stacked, one capacitor is formed by the capacitor patterns 103-1 to 103-8, and one helical antenna is formed by the antenna patterns 104-1 to 104-8. The capacitor and the antenna are connected to an IC chip 11. This invention can be applied to a noncontact IC card carrying out noncontact communication. <P>COPYRIGHT: (C)2010,JPO&INPIT |
