<P>PROBLEM TO BE SOLVED: To provide a communication device allowing downsizing and thinning a body of an electronic apparatus when being mounted in the electronic apparatus while maintaining communication characteristics. <P>SOLUTION: An antenna device includes: an antenna substrate 11 provided with an antenna coil 11a inductively coupled to a reader/writer 120; a magnetic seat 13 that is arranged at a position superposed on the antenna coil 11a formed on the antenna substrate 11, and that brings a magnetic field transmitted from the reader/writer 120 into the antenna coil 11a; a film-like protective member 15 that is laminated on surfaces other than surfaces where the magnetic seat 13 and the antenna coil 11a are superposed, and that covers the whole edges 13a and 13b of the magnetic seat 13. The magnetic seat 13 is inserted into a center portion 11c of the antenna coil 11a formed on the antenna substrate 11 so that the antenna coil 11a and the magnetic seat 13 are superposed on each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
