Zusammenfassung:A noise filter that is capable of efficiently removing noise even in a case where a ferrite core having two divided core portions is used. The noise filter includes a tubular ferrite core. The ferrite core includes two divided core portions. The two divided core portions are configured to be divided along divided end surfaces in an axial direction of the ferrite core. The two divided core portions include a platinum group metal in an amount of 0.5% to 2.0% with respect to the total weight of a ferrite powder.
