Abstract
A printing substrate having a spiral recess filled with conductive paste is placed on an insulation substrate. The conductive paste is transferred onto the insulation substrate, and is then sintered with the insulation substrate to form a coil pattern on a single surface of the insulation substrate. A non-magnetic section of non-magnetic material is formed around the coil pattern. The inductor device having above configuration has excellent attenuation characteristics in a high frequency band, while having a low profile because of a thinner magnetic section.
