クタンス素子とするには限界がある。(Prior Art and Problems to be Solved by the Invention) Most inductance elements conventionally used in the 100 KHz frequency band use a ferrite annular magnetic core. This kind of inductor? -) m inclination lv1+-+Dufu Tian Oil Textile Co., Ltd. Dingba Kogun Danpaku μl-7 #Sakai, and there is a limit to the miniaturization of the inductor. This is because as the frequency increases, due to the skin effect of magnetic flux, the effective magnetic flux is small relative to the volume of the magnetic core, and the inductance decreases. Therefore, in order to obtain a desired inductance value, it is necessary to increase the number of turns of the coil, and there is a limit to how small an inductance element can be made.
一方、電子回路の他の素子の分野ではＩＣからＬＳＩ化

が著しくチップの自動装着技術の普及が広まっている。On the other hand, in the field of other elements of electronic circuits, with the progress in semiconductors such as the transition from ICs to LSIs, there is a desire for smaller, thinner and thinner resistors and capacitors.

The inductance element is composed of a combination of an annular magnetic core and a winding wire, and as mentioned above, there are limits to miniaturization, so the industry has been eager for a new small, light and thin inductance element.

容積当たりのインダクタンス値が小さいという重大な欠
点を有している。In recent years, in order to reduce the size of inductance elements, a multilayer chip inductor has been devised, which is made of an outer iron type closed magnetic circuit toroidal in which ferrite and conductor are alternately laminated and fired. However, this multilayer chip inductor has drawbacks such as being too thick and not being thin enough, and the firing process is difficult to control, making it impossible to produce inexpensive mass-produced products.
It has a serious drawback of having a small inductance value per volume.

ンダクタンス素子を発明するに至った。(Means for Solving the Problems) In order to solve the above problems, the present inventors, as a result of intensive research, have created a completely new structure by combining high magnetic permeability amorphous metal fibers and insulated copper wires. We have succeeded in inventing an inductance element that is small, thin, and has a large inductance value per volume.

ダクタンス素子である。That is, the present invention is an inductance element characterized by having a woven fabric in which high magnetic permeability amorphous metal fibers and insulating coated copper wires are interwoven, and the insulating coated copper wires are electrically continuous. .

い。FIG. 1 shows an example of the configuration of the present invention. In Figure 1, amorphous metal fibers (indicated by l in the figure) are used as the warp yarns, and insulation-coated copper wires are used as the weft yarns at the edges of a mixed woven fabric (indicated by 2 in the figure). The wire is folded back to form one continuous copper wire. In the present invention, it is important that the direction of the current flowing through the copper wire is in the same circumferential direction around the amorphous metal fibers, so the warp and weft threads may be used in reverse combinations. Further, the structure of the woven fabric may be plain weave, twill weave, satin weave, etc., but plain weave structure in which the warp threads and weft threads intersect with each other in the greatest number of points is preferable.

される。The insulated copper wire only needs to maintain electrical continuity, and may be folded back as shown in Fig. 1, but as shown in Fig. 2, the insulated copper wire may not be folded back at the selvage of the fabric. Even if adjacent copper wires are electrically connected by joining them with solder or the like (indicated by 3 in the figure), the effects of the present invention can be realized.

る。In the figure, only one amorphous metal fiber and insulated copper wire are shown as warp threads or weft threads, but in order to obtain a desired inductance value or for a desired purpose, multiple pieces of each are bundled and warp threads are used. The structure may be formed as a weft. For example, if a bundle of two or more amorphous metal fibers is used as the warp thread, an element with a high inductance value can be obtained. Furthermore, if a bundle of multiple insulated copper wires is used as the weft thread, there will be less current loss at high frequencies, and an inductance element that can handle high currents will be possible.Furthermore, by using mutual inductance, it will be possible to reduce the direct current component. Can be used as an isolation transformer for cutting purposes.

維の成分は零磁歪近傍が好ましい。The high magnetic permeability amorphous metal fiber of the present invention includes a magnetic metal component (for example, iron, cobalt, nickel, or a mixture thereof) and a semimetal component necessary for amorphization (for example, silicon, boron, phosphorus, carbon, etc.). or a mixture thereof, etc.) is an amorphous fiber with a circular cross section. In addition, chromium is added to stabilize the properties.
Several atomic percent of manganese, niobium, etc. may be added. The diameter is usually 100 μm to 15 μm obtained by spinning in a rotating liquid.
Either use 0 μm amorphous metal fiber as is, or
Alternatively, it is also possible to use a material whose diameter has been reduced by die drawing, or a material which has been subjected to heat treatment to improve magnetic properties. Having a circular cross section has an extremely advantageous effect on workability, operability, flexibility, etc. when constructing a textile structure. Since the amorphous metal fiber constitutes a woven structure, it is preferable that the components of the amorphous metal fiber have near zero magnetostriction.

一にするのが好ましい。In order to make the woven fabric denser, it is preferable that the warp and weft yarns have the same diameter.
