Abstract

　磁性体コア（４）とフレキシブル基板（５）とを備えるアンテナコイル（２０２）を回路基板（９）に実装してアンテナ装置を構成する。磁性体コア（４）の主面と平行なコイル軸を有する第１のコイル部（２ａ）は第１のコイル（２１）と第３のコイル（２３）とで構成し、第２のコイル部（２ｂ）は第２のコイル（２２）と第４のコイル（２４）とで構成し、第１・第２のコイル部（２ａ，２ｂ）の間に導体非形成部（８）を設ける。フレキシブル基板（５）には突出部（６）に設けるとともに、この突出部（６）に第１～第４のコイル接続部を引き出す。このフレキシブル基板（５）の突出部（６）で回路基板（９）上の導体パターンに接続することによって各コイル同士の結線を回路基板上で行い、アンテナ装置を構成する。
