Abstract
The present invention provides an antenna coil which can be made smaller and intends to improve a receiving sensitivity in consideration of all directions. According to one embodiment of the present invention, an antenna coil including: a first coilhaving an X-axis coil wound on an X axis of a first core and a Z-axis coil wound on a Z axis of the first core, the thickness direction of the first core being determined to be the Z-axis, an axis orthogonal to the Z axis being determined to be the X axis; a second coilhaving a Y-axis coil wound around a second core, the second core having flanges at both ends; four external terminalseach connected to a corresponding end of the X-axis coil or the Z-axis coil and additionally provided on the first core; and two external terminalseach connected to a corresponding end of the Y-axis coil and additionally provided on the second core. The first coiland the second coilare arranged to be close to each other so that winding axis directions of the X-axis coil, the Y-axis coil, and the Z-axis coil are orthogonal to each other. The first coiland the second coilare integrally molded using an exterior resin, leaving part of each of the external terminals to be connected to an external circuit.
