Magnetic antenna and antenna device
There is provided a magnetic antenna and an antenna device that increase the packaging density of a portion where the magnetic antenna is mounted in an electronic apparatus, and suppresses degradation of antenna performance. A flexible substrate has first and second substantially spiral-shaped coil conductors formed thereon. Conductor-opening-side through holes are formed in the respective conductor openings of the coil conductors, and non-coil-conductor-forming-area through holes are formed in areas in which the coil conductors are not formed. First and second magnetic cores are arranged so as 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 in a direction from a second main surface side to the first main surface of the flexible substrate.
