Abstract

　フレキシブル基板(２３)には、巻回中心部を導体開口部(ＣＷ)とする渦巻状のコイル導体(２４)が形成されている。フレキシブル基板(２３)は、導体開口部(ＣＷ)を通る線に沿って磁性体コア(２２)を包むようにコ字状に折り曲げられている。磁性体コア(２２)は、その端面がフレキシブル基板(２３)の折り曲げ部に対向する状態で配置され、その端面のうちフレキシブル基板(２３)の折り曲げ部のコイル導体部(ＣＣ)に対面する部分に、コイル導体部(ＣＣ)から離間する切欠形状部(２２ａ),(２２ｂ)が設けられている。この構成により、必要な巻回数を確保し、また、磁性体コアの磁束透過面付近のアンテナの開口を広げて磁束の放射効率を高める。
