欠点がある。In most conventional inductance elements, the magnetic core 1 and the winding 2 are separate C2, as shown in Figure 'm1.
The structure was such that a bobbin 5, on which a winding 2 was previously applied, was attached to a magnetic core 1. For this reason, the bobbin 3 is essential, the number of parts is large, it is difficult to make the shape smaller and thinner, and assembly is troublesome.・In addition to the one shown in this example, there are also thin film inductors, but this type has a small obtained inductance value, and the shape and structure are specified and not arbitrary, so the range of applications is narrow and it is not flexible. It has the disadvantage of lacking sexual sensibility.

利点が得られる。5 is a conductor which has been subjected to insulation treatment 1 and arranged as ii) on the surface C of the magnetic distribution body 4. In this embodiment, the conductor 5 is a linear conductor, and has a structure in which a plurality of conductors are arranged at intervals and buried in an insulating resin 6.

、高密度笑装化を図るのに有効である。In the inductance element g2 of the above embodiment, an inductance component is generated due to the interaction between the magnetic field of the current flowing through the conductor 5 and the magnetic body 4, and it functions as an inductor. In this case, since the insulated conductor 5t is provided along the surface of the thin plate-like magnetic body 4, it can be used as an inductor without requiring a magnetic core. Moreover, since it has a thin and flat shape, it is effective in making one circuit thinner, smaller, and more densely packaged.

性である。In addition, since the magnetic body 4 is in the form of a flexible thin plate, the shape is highly variable, and a highly flexible inductance element can be realized. By forming the conductor 5 into a ring shape having an appropriate diameter and connecting the conductor 5 in series in the narrowest parts, a ring-shaped inductance element having an even larger inductance value can be easily realized. Also,#! By installing a ring-shaped inductance element as shown in Figure 6 (g=12, m5) near the 7th gap Ga of the magnetic core, an inductor with unique ampere-turn-inductance characteristics as shown in Figure 7 is realized. You can also. @7 Figure 6; The ampere-turn-inductance characteristic shown is that the inductance value is extremely high in the low current region, and then the value decreases sharply at a certain current value, and the inductor maintains that small inductance value until the Ogame style range. It shows what you can get. These characteristics suppress abnormal increases in output voltage or frequency during light loads, improve output stability, and prevent intermittent oscillations in choke coils, output filters of switching power supplies, or power transformers of flyback converters. This is a necessary characteristic to prevent abnormal operation.
