Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a coil antenna, having a magnetic core provided with an adequate structure when it is set freely bendable. SOLUTION: The coil antenna comprises a magnetic core and a coil wound around the magnetic core. The magnetic core is composed of a mixture of soft magnetic substance powder and organic binder, and is formed so as to have flexibility and to be freely bendable. Each soft magnetic substance powder is coated with an insulator layer. As the insulator layer is thus provided, the coil antenna can have proper μ'-characteristics in a low medium wave band, even when it is bent during use. COPYRIGHT: (C)2005,JPO&NCIPI
