い。FIG. 5 shows an embodiment in which a magnetic frame 6 is provided outside the flat magnetic body 1 to form a box shape together with the upper flat plate 3. This reactor can have a smaller gap in the magnetic path than the axle shown in FIG. 1, can create an axle with a large inductance, and has no leakage of magnetic flux to the outside.

とることが有効である。Although there is no particular description of how to draw out the conductor layer terminals in the above embodiments, if coated copper wire is not used, the conductor layer should be crossed through an insulating layer, or if accuracy of dielectric strength and flatness is required. 9 (as shown in the barrel), a through hole 7 is provided in the flat magnetic material 14 to connect the terminal conductor 26 of the conductor layer.
An effective method is to provide a groove 8 in the flat magnetic material l and pass the terminal conductor 26 through the groove 8, as shown in Fig. 9.

７なく・。The present invention constitutes a flat glue axle by forming a spiral conductor layer between two flat magnetic bodies, and the outer shape is very gate-shaped, allowing multiple glue axles to be integrated into a small size. It can be used effectively to downsize electronic devices. Also, by using a flat magnetic material, 61°'da'''' can be cut by 7'' or less.
