<p><P>PROBLEM TO BE SOLVED: To provide a coil antenna having high sensitivity when internal components are resin-sealed, in which a harness pull-out strength and insulation in an electrical connection part are ensured, and which is formed small and thin so as to be put into a narrow space. <P>SOLUTION: In a coil antenna comprised of an inductor 1, constituted of a magnetic core 2 and a coil with a winding 3 wound around the magnetic core 2 and a harness 4 including an insulated coating for supplying power to the inductor 1, the entire outer periphery of the inductor 1 and an electrical connection part between the inductor 1 and the harness 4 is replaced with a first resin 7 or the electrical connection part between the inductor 1 and the harness 4 is replaced with a second resin 8 so as to be coated integrally. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
