Abstract

　第１のコイル体と第２のコイル体との間のインダクタンス差を可能な限り小さくして、Ｓcd２１特性の改善を図ったコモンモードチョークコイルを提供する。 　磁性体基板２－１と絶縁体３と絶縁体３に内包されたコイル体４，５と磁粉入り樹脂６と磁性体基板２－２と外部電極７－１～７－４とを備える。コイル体４の引出線４１，４２は、コイル本体部４０の外端，内端からそれぞれ引き出された後、巻き方向に対して逆方向に折り曲げられている。一方、コイル体５の引出線５１，５２は、コイル本体部５０の外端，内端からそれぞれ巻き方向に対して同方向に引き出されている。そして、磁粉入り樹脂６が、絶縁体３の充填孔３０Ａ，３０Ｂに充填されて、磁性部６１が引出線４１と最外周の電極線４０Ａとの間隙に形成され、磁性部６２が引出線４２と最外周の電極線４０Ａとの間隙に形成されている。
