Abstract
The present invention provides a receiving antenna coil capable of realizing both improvement in the reception characteristic and miniaturization. In a receiving antenna coil, at least one of an X-axis winding core part and a Y-axis winding core part is formed in a plurality of bars. While increasing occupancy of the winding core parts (the X-axis winding core part and the Y-axis winding core part) in a region in the XY plane surrounded by a Z-axis receiving coil, the length of the winding core parts can be assured long. Further, since the X-axis winding core part and the Y-axis winding core part are provided in the same plane, the height of the core is suppressed, and the dimension of the entire receiving antenna coil can be suppressed.
