A noise filter (10) is equipped with a plurality of conductors (20) having respective winding portions (21) and a ring-shaped core (30) which is inserted through the winding portions of the a plurality of conductors and made of a magnetic material. The ring-shaped core is composed of a pair of divisional cores (41) and (42) which are combined together by joining each pair of joining surfaces (43) and (44), located at each end, of the pair of divisional cores and. The one divisional core is straight and is inserted through the winding portions of the a plurality of conductors. The other divisional core has partition walls (45) each of which is located between adjacent ones of the a plurality of conductors, projects toward the one divisional core, and serves to form a magnetic path between the partition wall and the one divisional core.
