PROBLEM TO BE SOLVED: To provide a three-axis antenna coil which makes a high reception sensitivity compatible with high impulse resistance.SOLUTION: In the three-axis antenna coil, three coils are wound around a core 10 in such a manner that winding axes are orthogonal with each other. The three-axis antenna coil comprises: the core 10; an X-axis coil 21 and a Y-axis coil 22 that are wound around the core; a plurality of first metal terminals 31 including bundling parts 31a to which terminals of the X-axis coil and the Y-axis coil are connected; a plurality of second metal terminals 41 including bundling parts 41a; a sheath body 51 in which the core 10, a part of the first metal terminals 31 including the bundling parts 31a and a part of the second metal terminals 41 excluding the bundling parts 41a are embedded; and a third coil 23 which is wound around an outer periphery of the sheath body 51 and of which the terminal is connected to the bundling part 41a of the second metal terminal 41 exposed from the sheath body 51.SELECTED DRAWING: Figure 2 |
