Abstract

　１次側コイルと２次側コイルとのインダクタンス値に差異をなくした構造にして、実装方向に拘束されることなく所望特性の動作を発揮する積層型トランス部品を提供する。 　１次側コイル４及び２次側コイル５を内部に有するチップ体２と第１～第４外部電極３－１～３－４とを備える。１次側コイル４は本体部４５Ａと第１引出線４６と第２引出線４７とで構成され、２次側コイル５は本体部４５Ａと第３引出線５６と第４引出線５７とで構成される。本体部４５Ａの第１突出部４５ａと第２突出部４５ｂは直線Ｌ１上に配されている。第１突出部４５ａと第２突出部４５ｂとの先端部間の中心に位置し且つ積層方向に垂直な中心線Ｌ２に関して、第１引出線４６と第４引出線５７とが線対称な形状に設定され、第２引出線４７と第３引出線５６も、中心線Ｌ２に関して線対称な形状に設定されている。
