A three-axis antenna containing: a bobbin (30) of a first material, for housing a core (20) of a second material, the bobbin having an top flange (31) and a bottom flange (32) both of which include four flange pieces (31 a, 31 b, 31 c, 31 d, 32a, 32b, 32c, 32d) at both ends of the winding column in the thickness direction of the core; a first coil and a second coil (41, 42) wound in the spaces (34ab, 34 bc, 34cd, 34ad) between the flange pieces to cross each other at the upper and lower surfaces of the core; and a third coil (43) wound at the side surface of the core and between the top flange and the bottom flange. The bobbin may be formed of a synthetic resin. |
