Abstract
A noise filter has a magnetic core having a pair of magnetic core members each with a coupling surface. Each of the magnetic core members has a dented portion so arranged that, when the magnetic core members are closed together on the coupling surfaces, a closed magnetic path and an opening for inserting therethrough a cable are formed between the magnetic core members. An electrically insulating outer sheath member is disposed on an outer surface of each of the pair of magnetic core members. An electrically insulating coating member is disposed on an inner wall surface of each of the dented portions.
