摘要： PROBLEM TO BE SOLVED: To reduce loss in a DC superimposed high frequency circuit, a low frequency superimposed high frequency circuit, and the like.SOLUTION: Copper wires each having a magnetic plating layer formed on the surface are mixed and aggregated to obtain a wire. Since magnetic material plated copper wires are disposed, DC resistance or low frequency resistance can be reduced. Since a magnetic field produced by a flowing current is interrupted by the magnetic material plating layer and does not enter the copper wire part easily, increase in copper loss due to proximity effect at high frequency can be suppressed. Consequently, loss can be reduced in a DC superimposed high frequency circuit, a low frequency superimposed high frequency circuit, and the like.
摘要翻译： 要解决的问题：减少DC叠加高频电路，低频叠加高频电路等中的损耗。解决方案：将表面上形成有磁性镀层的铜线混合并聚集，以获得线 。 由于设置有磁性材料电镀铜线，因此可以降低直流电阻或低频阻抗。 由于由流动电流产生的磁场被磁性材料镀层中断，并且不容易进入铜线部分，所以可以抑制由于高频下的接近效应引起的铜损失的增加。 因此，在DC叠加高频电路，低频叠加高频电路等中可以减少损耗。

摘要： PROBLEM TO BE SOLVED: To provide an insulated wire excellent in high-frequency characteristics and an insulation property.
SOLUTION: The insulated wire includes: an assembled wire (11) wherein a whole cross-section outline becomes round by assembling parallel seven enameled wires (4) each having a non-circular cross-section outline; and a first insulating coating (1) wherein an insulating tape is wound around an outer periphery of the assembled wire (11) so as to bundle the assembled wire (11). The insulated wire can reduce high-frequency loss in comparison with a single wire having the same conductor cross-section area, and can lessen an outer diameter in comparison with a litz wire having the same conductor cross-section area. Further, variations in outer shapes of the insulated wire can be lessened since bundling force of the assembled wire is easily maintained by winding the insulating tape without stranding, and the insulated wire is excellent in the insulation property.

摘要： PROBLEM TO BE SOLVED: To reduce a loss in a high frequency circuit.
SOLUTION: A magnetic plated layer is formed on the surface of a copper wire, and an insulating coating is formed on the surface of the magnetic plated layer to obtain a copper wire (10) plated with magnetic material having insulating coating. A plurality of the plated copper wires are braided into a tubular shape and processed into a flat shape. Since a magnetic field made by a current flowing in the copper wire is interrupted by the magnetic plated layer of the wire (10) plated with magnetic material having insulating coating, and it becomes difficult for the magnetic field to enter the copper wire portion, the increase of copper loss by proximity effects in a high frequency can be suppressed, and the loss in the high frequency circuit can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a spiral coil which is manufactured at a low cost and reduces the high-frequency loss resulting from the eddy current loss. SOLUTION: A braided wire having a flatly crushed shape wherein strands is insulated, or a plain stitch wire wherein strands is insulated, is wound in such a direction that the surfaces of the longer side are superimposed, or is spirally wound in such a direction that the surfaces of the shorter side are superimposed to constitute the spiral coil. In this case, because an ordinary braided wire or an ordinary plain stitch wire is used, it is manufactured at a low cost and the high-frequency loss is reduced. The spiral coil, which is wound in such a direction that the surfaces of the longer side are superimposed, has more windings with respect to the same coil diameter than that in the round wire case. The spiral coil, which is wound in such a direction that the surfaces of the shorter side are superimposed, has a coil thickness thinner than that in the case wherein a round wire of the same cross-sectional area is used.

摘要： PROBLEM TO BE SOLVED: To reduce a loss in a high-frequency circuit superimposed with a direct current, and in a high-frequency circuit or the like superimposed with a low-frequency. SOLUTION: A plurality of insulation covered copper wires (10) plated with magnetic material are collected while twisted in a plurality of numbers or while untwisted. Since the entire surface is arranged with the insulation covered copper wires (10) plated with the magnetic material, resistance under the direct current or the low frequency can be reduced. Since the magnetic field generated by a flowing current is intercepted by the magnetic material plating layer of the insulation covered copper wires (10) plated with the magnetic material, and made difficult to enter the copper wire portion, an increase in copper loss due to proximity effect in the high-frequency can be suppressed, and accordingly, the loss in the high-frequency circuit superimposed with the direct current and the high-frequency circuit or the like superimposed with the low-frequency can be reduced.
