PROBLEM TO BE SOLVED: To provide an antenna coil that has a simple structure and high sensitivity, and can be thinned. SOLUTION: The antenna coil 1 comprises an XY coil unit 5 in which X- and Y-axis coils 3, 4 are wound around a core 2, and a Z-axis coil 6 wound around the XY coil unit 5. In this case, three coils comprising the X-, Y-, and Z-axis coils 3, 4, and 6 are arranged with a mutually orthogonally crossed direction as an axis. The XY coil unit 5 is integrated with the Z-axis coil 6 by a resin section 7 insertedly formed around the XY coil unit 5 and the Z-axis coil 6. COPYRIGHT: (C)2006,JPO&NCIPI
