| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an inexpensive coil antenna magnetic core, coil antenna, and coil antenna module excellent in resistance to impact and in flexibility. SOLUTION: An inexpensive coil antenna magnetic core 1 can be manufactured using ferrite core whose raw material cost is inexpensive and in which the magnetic characteristics as the coil antenna magnetic core 1 do not deteriorate even when an impact is exerted on the coil antenna magnetic core 1 from outside and the change in the magnetic characteristics as the coil antenna magnetic core 1 is small even when the coil antenna magnetic core 1 is bent, by laminating a tape 3 having an adhesive layer 3b on the upper surface and the undersurface of a plate-shaped ferrite core 2 and forming a sheet 8 by breaking the ferrite core 2 covered with the tape 3 into plate-shaped chips.
