PURPOSE:To reduce magnetic resistance, and to obtain high Q by interposing an insulating layer made of a nonmagnetic material between conductor patterns. CONSTITUTION:Conductor patterns 14 are formed into a magnetic material 13, and the patterns 14 form wound coil patterns. The insulating layers 15 made of the nonmagnetic material are formed among the patterns 14. The insulating layer 15 is formed by the nonmagnetic material, such as alumina, steatite, Si dioxide, etc., and it is preferable that the permittivities of these conductors are lowered. According to such constitution, a magnetic circuit is formed in the magnetic material, and is difficult to be formed to sections among conductors. Consequently, since the reluctance of the conductors reduces, the resistance of the wound conductor patterns also minimizes, and Q value can be improved. |
