Abstract

　大型化を招来することなくノイズ抑制効果の大きなＬＣ複合電子部品を得る。 　第１及び第２コンデンサ部（１０），（２０）と第１及び第２コイル部（３０），（４０）とを積層した積層体からなるＬＣ複合電子部品であって、４組のＬＣ共振回路を内蔵している。コイル電極（３１ａ）と共振調整電極（５１ａ）との間にノイズ循環容量（Ｃ２１）が形成され、コイル電極（３１ｃ）と共振調整電極（５１ｂ）との間にノイズ循環容量（Ｃ２２）が形成される。コイル電極（４２ａ）と共振調整電極（５３ａ）との間にノイズ循環容量（Ｃ２３）が形成され、コイル電極（４２ｃ）と共振調整電極（５３ｂ）との間にノイズ循環電極（Ｃ２４）が形成される。引出し電極（３２ｂ），（４１ｂ）間にノイズ循環電極（Ｃ２５）が形成され、引出し電極（３２ｄ），（４１ｄ）間にノイズ循環電極（Ｃ２６）が形成される。
