To provide an electric reactor of which an electric resistance of a connection part of a winding part and a bus bar is easily increased.SOLUTION: An electric reactor comprises: a coil having a first winding part and a second winding part which are formed by winding a wire; and a magnetic core that is arranged in an inner side and an outer side of the first winding part and the second winding part, and forms an annular close magnetic path, and comprises a conductive bus bar which electrically connects a coupling end part of the first winding part and a coupling end part of the second winding part. The bus bar is formed by bending a plate-like piece in an U-shape like to a thickness direction, and includes: a first U-shape metal fitting part into which the coupling end part of the first winding part is embedded; a second U-shape metal fitting part to which the coupling end part of the second winding part is embedded; and a coupling metal fitting part connecting the first and second U-shape metal fitting parts.SELECTED DRAWING: Figure 3 【課題】巻回部とバスバーとの接続部の電気抵抗が高くなり難いリアクトルを提供する。【解決手段】巻線を巻回してなる第一巻回部及び第二巻回部を有するコイルと、前記第一巻回部及び前記第二巻回部の内外に配置され、環状の閉磁路を形成する磁性コアと、を備えるリアクトルであって、前記第一巻回部の連結端部と前記第二巻回部の連結端部とを電気的に繋ぐ導電性のバスバーを備え、前記バスバーは、板状片がその厚み方向にＵ字状に屈曲することで形成され、前記第一巻回部の連結端部が嵌め込まれる第一Ｕ字金具部と、板状片がその厚み方向にＵ字状に屈曲することで形成され、前記第二巻回部の連結端部が嵌め込まれる第二Ｕ字金具部と、前記第一Ｕ字金具部と前記第二Ｕ字金具部とを繋ぐ連結金具部と、を備える。【選択図】図３
