In FIG. 1, 11 is an insulating magnetic material such as ferrite, which has a ring shape. Furthermore, a spiral groove 12 is carved on the surface. When ferrite is used as the magnetic body 11, it is manufactured by molding it with a molding machine and firing it, but at the same time grooves 12'' are also carved. The conductor I3 is formed by a method such as vapor deposition of a metal material such as copper or aluminum. Note that FIG. By forming the conductor 11, an inductance circuit as shown in Figure 2 (a), for example, is constructed.

When installing and connecting the conductor 110 in the groove 12 to the conductor/detail turn 21 on the printed wiring board 21, the connection is easy because the both ends of the conductor 110 in the groove 12 can be directly soldered to the conductor/detailed turn 21 on the printed wiring board 21. Or should the winding terminals be pre-solder plated? There is no need to do work such as connecting it to the pin terminal of the bottle. Additionally, since the conductor 13 can be soldered to the conductor/transformer 23 even at its intermediate portion, there is no need to make any changes to the inductance element itself, and there is no need to prepare intermediate parts or decals in advance. A ratio autotransformer can be easily configured.
