Abstract:
1. A magnetic antenna for mounting on an electronic apparatus having a circuit substrate, comprising: a flexible substrate having first and second coil conductors formed thereon; and first and second magnetic cores, wherein the first and second coil conductors are formed in spiral shapes having conductor openings at the respective centers thereof, wherein the flexible substrate has conductor-opening-side through holes, through which the magnetic cores extend, formed in the conductor openings, the flexible substrate including non-coil-conductor-forming-area through holes, through which the magnetic cores extend, formed in areas in which the coil conductors are not formed, wherein the first and second magnetic cores are arranged to extend through the respective conductor-opening-side through holes from a first main surface of the flexible substrate and to extend through the respective non-coil-conductor-forming-area through holes from a second main surface of the flexible substrate, and wherein the first main surface of the flexible substrate is positioned to face the circuit substrate in the electronic apparatus.
