巻線していた。BACKGROUND OF THE INVENTION A conventional coil component of this type has a structure as shown in FIG. In FIG. 3, 1 is an insulating tape, and 2 is a band-shaped conductor, for example, a copper foil tape, and these are overlapped and wound.
発明が解決しようとする問題点
このような従来の構成では、帯状導体２に高周波交流電
流が流れると近接効果の影響で帯状導体２内に電流密度
の不均衡が生じ、その実効抵抗が増加するため損失が増
大するという問題があった。Problems to be Solved by the Invention In such a conventional configuration, when a high-frequency alternating current flows through the strip conductor 2, an imbalance of current density occurs in the strip conductor 2 due to the influence of the proximity effect, and its effective resistance increases. Therefore, there was a problem that losses increased.
本発明はこのような問題点を解決するもので、近接効果
の影響を低減し、高周波実効抵抗の増加を抑え、損失の
増大を防ぐことを目的とするものである。The present invention is intended to solve these problems, and aims to reduce the influence of the proximity effect, suppress an increase in high-frequency effective resistance, and prevent an increase in loss.
問題点を解決するための手段
この問題点を解決するために本発明は、帯状導体の片側

のである。Means for Solving the Problem In order to solve this problem, the present invention has a configuration in which a strip-shaped magnetic material is installed on one or both sides of a strip-shaped conductor and wound.
作用゛
この構成により、高周波電流によって生じた磁界が帯状
磁性体に集中するため、近接する帯状導体への電磁誘導
作用が抑えられ、近接効果を低減することとなる。Effect: With this configuration, the magnetic field generated by the high-frequency current is concentrated on the strip-shaped magnetic material, so that the electromagnetic induction effect on the adjacent strip-shaped conductor is suppressed, and the proximity effect is reduced.

比較図である。Embodiment FIG. 1 shows a coil in which a strip-shaped magnetic material is inserted according to an embodiment of the present invention, 3 is an insulating tape, 4 is a strip-shaped conductor made of, for example, copper foil tape, and 5 is a strip-shaped magnetic material, such as a tape-shaped one. It is a processed silicon copper plate. Since the magnetic field generated by the high-frequency current flowing through the strip-shaped conductor 4 is concentrated on the strip-shaped magnetic body 6, the electromagnetic induction effect on the neighboring strip-shaped conductor 4 is suppressed, and the proximity effect is reduced. FIG. 2 is a diagram comparing the rate of increase in high frequency effective resistance between one conventional coil component and the coil component according to the present invention.
