Patent ID: 8451184

Claim:
An antenna coil comprising: a first coil having 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 coil having a Y-axis coil wound around a second core, the second core having flanges at both ends; four external terminals each 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 terminals each connected to a corresponding end of the Y-axis coil and additionally provided on the second core, wherein the first coil and the second coil are 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, wherein the first coil and the second coil are integrally molded using an exterior resin, leaving part of each of the external terminals to be connected to an external circuit.
