<p><P>PROBLEM TO BE SOLVED: To provide an antenna structure and a radio wave receiver which are easily manufactured and achieve good receiver sensitivity even if a metal member is placed nearby, and to provide a manufacturing method of the antenna structure. <P>SOLUTION: A conducting wire is wound around a center part of a core 21 formed by a magnetic material to form a coil 22. An end part of the core 21 is coated by a first coating member 24 formed by a material including the magnetic material, and the center part of the core 21, where the coil 22 is formed, is coated by a second coating member 25 formed by a material including the magnetic material. Since a clearance 26 is provided between the first coating member 24 and the second coating member 25, the structure reduces magnetic flux leaking to the side of a metal member and prevents the occurrence of eddy current even if the metal member is located nearby. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
