摘要

Ceramic inductive element comprises a magnetic ceramic body made of either Ni-Cu-Zn ferrite or Ni-Cu ferrite containing 5-150 ppm sulfur, 5-150 ppm chlorine and 5-100 ppm sodium. The element is produced by simultaneously calcining a magnetic ceramic body and an inductive resistor formed from silver. Preferred Features: The inductive resistor contains a coil laminated in the magnetic ceramic body.
