PROBLEM TO BE SOLVED: To provide a transmission antenna coil which can be made low-profile. SOLUTION: The transmission antenna coil is provided with a magnetic material core 11, a bobbin 12 housing the core 11 and a conductor 15 wound around the outer peripheral part of the bobbin 12. Flange parts 14a, 14b, 14c and 14d for sectioning the wound parts 15a, 15b and 15c of the conductor 15 are formed at the outer peripheral part of the bobbin 12, and window-like opening parts 13a, 13b and 13c exposing the surface of the magnetic body core 11 in a mounting height direction are formed at the wound parts 15a, 15b and 15c. The conductor 15 is wound around an area sectioned by the flange parts 14a, 14b, 14c and 14d and formed as one coil. COPYRIGHT: (C)2005,JPO&NCIPI
