PROBLEM TO BE SOLVED: To provide a magnetic antenna that is thinned as a whole while including a magnetic core and a flexible substrate having a coil conductor, and an antenna device including the same.SOLUTION: A flexible substrate 23 has a coil conductor 24. The coil conductor 24 encircles a conductor opening CW and has a spiral shape that a part thereof detours in a rectangular three-sided shape (a U-shape) in the center direction of the conductor opening CW. The flexible substrate 23 has a magnetic core insertion hole 26 along the detour shape in the conductor opening CW. The magnetic core 21 is inserted into the magnetic core insertion hole 26. By this, the coil conductor 24 is arranged around the magnetic core 21 without folding back the flexible substrate 23. |
