Summary:To provide a noise filter capable of achieving higher inductance while suppressing the overall height (direction along the length of a magnetic leg) and a magnetic core used therefor.SOLUTION: A magnetic core used for a noise filter includes two magnetic legs and two connections connecting the ends of the two magnetic legs, and at least one of the connections includes an overhang portion in which at least a partial region in the length direction connecting the magnetic legs is extended outward in the width direction of the connections.SELECTED DRAWING: Figure 1 【課題】全体の高さ（磁脚の長さ方向に沿う向き）を抑えながらも、より高いインダクタンスを実現することのできるノイズフィルタと、これに使用する磁性コアを提供すること。【解決手段】ノイズフィルタに使用される磁性コアであって、２つの磁脚と、当該２つの磁脚の各端部間を接続する２つの接続部とからなり、少なくとも何れかの接続部は、前記磁脚同士を接続する長さ方向の少なくとも一部の領域を、当該接続部の幅方向外側に張り出させた張出部を備えている磁性コアとする。【選択図】図１
