Summary:PROBLEM TO BE SOLVED: To provide an inductor device which is easy to manufacture.SOLUTION: An inductor device 1 includes: a plurality of unit substrates 10a-10c each having an electrical insulating sheet 11 with a through hole 12 and a coil 14 which is arranged on the sheet 11 so as to be wound around the through hole 12; and a core 20 which is formed of a magnetic material and is inserted through the respective through holes 12 of the unit substrates 10a-10c. The plurality of unit substrates 10a-10c are arranged so that coils 14 of adjacent unit substrates overlap via the core 20. The coils 14 of the plurality of unit substrates 10a-10c are electrically connected in series. 【課題】製造が容易なインダクタ装置を提供する。【解決手段】インダクタ装置１は、貫通孔１２を有する電気絶縁性のシート１１と、貫通孔１２の周囲を捲回するように１１シート上に配置されたコイル１４と、を有する複数の単位基板１０ａ〜１０ｃと、磁性材料により形成され、単位基板１０ａ〜１０ｃそれぞれの貫通孔１２に挿通されるコア２０と、を備え、複数の単位基板１０ａ〜１０ｃは、隣接する単位基板のコイル１４が、コア２０を介して重なるように配置され、且つ、複数の単位基板１０ａ〜１０ｃのコイル１４は、電気的に直列に接続される。【選択図】図１
