(Prior Art) In recent years, the frequency of electricity used has been increased in order to improve the efficiency and size of electronic devices and electromagnetic devices. When a high-frequency current is passed through the coil, the effects of the skin effect and proximity effect of the wire become large. To reduce this effect,
Conventionally, as a coil wire material, a litz wire formed by concentrically or collectively twisting a plurality of element wires (for example, enameled wire), a litz wire obtained by crushing the twisted wire into a rectangular shape, or a cotton thread or a silk thread on the outer circumference of the twisted wire A litz wire in which a fiber such as a resin thread is wound and coated with insulation or a resin-insulated litz wire by an extrusion method is used. By the way, the outer periphery of the litz wire is further coated with an insulating coating to improve the withstand voltage and to prevent scratches on the wires that make up the litz wire when the wire is processed into a coil. This is for improving the sex. Among the litz wires, the one formed by subjecting the outer peripheral insulating layer to resin insulation by an extrusion method has properties particularly excellent in withstand voltage and workability.

(考案が解決しようとする課題) しかし、前記リッツ線は次のような問題があった。(Problems to be solved by the invention) However, the Litz wire has the following problems.

. Among the litz wires, the one formed by extruding the common insulation layer with resin by extrusion method has twisted wires when the number of strands is 8 or more, and twisting is deformed due to winding after twisting or narrowing during extrusion, resulting in electrical characteristics. Has the disadvantage of decreasing. For this reason, at present, only 7 concentric twisted litz wires with less twist deformation can be manufactured, and more litz wires cannot be manufactured.

. In the case of crushing the twisted wire into a rectangular litz wire, when the stranded wire is crushed, the twist is likely to be deformed or loosened, and the insulation of the wire may be damaged, and if that happens, the electric Not only the characteristics deteriorate, but also the shape of the litz wire in the longitudinal direction becomes non-uniform, the shape when formed into a coil is not stable, and the space factor is poor.

In addition, the litz wire, which is obtained by crushing the twisted wire into a rectangular shape, is easy to deform and disperse when crushed, and since it is a stranded wire and has a large flexibility, it is necessary to apply uniform outer insulation. However, the electrical characteristics also deteriorate in this respect.

(Operation) In the flat wire for coil of the present invention, multiple parallel wires 4 formed by stacking a plurality of insulating wires 3 having the insulating film 2 in parallel in a plane and adhering them to each other are stacked. To form a laminated body 6 having a rectangular cross-sectional shape, and the outer peripheral insulating coating layer 5 is formed on the entire outer circumference of the laminated body 6 or at appropriate intervals so as to have a rectangular sectional shape along the outer shape of the laminated body 6. Therefore, unlike the conventional litz wire in which an insulating layer is directly applied to the outer circumference of the stranded wire, the strands are not distorted or deformed after being twisted, and the common insulation is stable. Moreover, since two or more multi-parallel lines 4 are laminated so as to have a rectangular cross-sectional shape, the space factor of the coil is improved and the coil shape is stabilized. In addition, since the outer peripheral insulating coating layer 5 is flexible enough to be wound in a coil shape, the coil can be easily formed. In the present invention, the flat wire for a coil in which the outer peripheral insulating coating layer 5 is partially provided on the outer periphery of the laminated body 6 of the multiple parallel wires 4 at intervals is particularly excellent in flexibility and is therefore particularly easy to wind in a coil shape. . Further, when a coil is formed as shown in FIG. 3 (b), a gap 7 is formed in a portion where the outer peripheral insulating coating layer 5 is not applied, so that heat generated when the coil is energized generates the gap 7.
