A three-axis antenna includes first to third antenna coils (21a,21b,21c) which include planar coils wound around a winding axis (N) and sheet cores (41,42,43) which are inserted into a central hole of each planar coil, respectively. Each antenna coil is arranged not to be overlapped. The plane of each planar coil is formed on the same plane. The axis direction of each sheet core of the first to third antenna coils crosses each other to form an angle of 120 degrees. |
