摘要： A wire harness includes: a wire part including a plurality of electric wires gathered in a same direction; and a shield member which collectively surrounds an outer periphery of the wire part. The shield member is disposed to be interposed between adjacent electric wires of the plurality of electric wires in the wire part. The adjacent electric wires in the wire part are arranged at a predetermined interval such that a predetermined value of electrostatic capacitance is established between the electric wires.

摘要： 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.

摘要： A noise reduction unit (100) is equipped with a noise filter (10), a housing (80) which houses the noise filter, and a sealing material (90) which is charged in the housing. The noise filter is equipped with conductors (20) having respective winding portions (21) and a ring-shaped core (30) which is made of a magnetic material and is inserted through the winding portions of the conductors. In the housing, a mounting portion (83) for the ring-shaped core has recesses (84) that are recessed in a direction going away from the ring-shaped core and support portions (83b) that support the ring-shaped core so that gaps (S) are formed between the ring-shaped core and the bottom surfaces of the respective recesses. The sealing material goes into the gaps and comes into contact with both of the ring-shaped core and the bottom surfaces of the recesses in the mounting portion.

摘要： A wire harness includes a wire portion formed by arranging three wires in the same direction, the respective wires having conductors and insulators coating outer circumferences of the conductors, and a braided wire. The three wires of the wire portion and the braided wire are disposed such that the braided wire is interposed between two wires of the wire portion adjacent to each other along a circumferential direction around a central axial line of the wire portion on a cross section of the wire harness when viewed from an axial direction along the central axial line, on a side of the central axial line from outer circumferential-side tangents connecting the conductors of the two wires.
