TRANSMISSION ANTENNA COIL

摘要

PROBLEM TO BE SOLVED: To provide a transmission antenna coil of a low Q value and a wide band in which inductance is not increased even when output is increased by increasing the winding number of a conductor without damaging thinning. SOLUTION: The transmission antenna coil is provided with a magnetic body core 11, a bobbin 12 housing the core 11 and the conductor 15 wound around the outer peripheral part of the bobbin 12. The conductor 15 is wound (wound parts 15a and 15b) between flange parts 14a and 14b and between flange parts 14c and 14d across a non-wound part 16a between the flange parts 14b and 14c and is formed as one coil.
