Claims (1)
- 電気絶縁性の磁性層と導体パターンが交互に積層され前記導体パターンが順次接続されることで、磁性体中で積層方向に重畳しながら螺旋状に周回するコイルが形成され、該コイルの両端がそれぞれ引出導体を介して積層体チップ外表面に引き出され電極端子に接続されている積層インダクタにおいて、
コイルの一部を形成する導体パターンの層とそれに間隔をおいて重なり合う導体パターンの層の間、及びそれに繋がりコイルの外側全体に広がるように磁性層に代えて電気絶縁性の非磁性層が設けられ、且つこのような非磁性層が2層以上、積層体の中心に対して積層方向で対称的に位置し、それによってコイルの内側部は全て磁性体として磁束が通りやすくし、コイルの外側は磁性体の間に配置された前記非磁性層によって磁束の通りが制御されるようにしたことを特徴とする積層インダクタ。
