PROBLEM TO BE SOLVED: To provide an antenna coil winding structure in an antenna rod capable of winding an antenna wire longer than the conventional one on an antenna wire support member of the same length without changing the length of an antenna coil, a coil diameter, a winding pitch, and the diameter of the antenna wire support member, etc., or shortening the antenna wire support member, while keeping the conventional winding length. SOLUTION: In the antenna coil winding structure, the antenna wire is wound in coils on the columnar antenna wire support member. The outer periphery of transverse plane of the antenna wire support member includes projected and recessed parts. The antenna wire is wound in coils along the shape of the outer peripheral surface of the antenna wire support member. COPYRIGHT: (C)2007,JPO&INPIT
