Abstract
The invention can provide a miniaturized noise filter. The noise filter for reducing noise comprises a coil with a conductive wire (2) wound around a core (1); a case (6) formed of an insulating material receiving the coil; a bracket (8) of a magnetic material forming a flux path of magnetic flux generated from the coil, which places the case thereon, which has a pair of end plates (12a, 12b) disposed opposite to both ends of the core of the coil respectively through a gap of a predetermined distance, and which has a bottom plate (8a) disposed between the pair of the end plates; and an input/output terminal (3a, 3b) for the coil.
