To attain ceramic electronic parts for high-frequency use which have a small magnetic loss and do not yield structure destruction even if they are produced by simultaneously firing a magnetic material and a conductive material including inexpensive Cu as principal components, and a method for manufacturing the ceramic electronic parts.
A magnetic material ceramic is formed with a garnet-type ferrite-based material as a principal component which does not contain bismuth, and includes a Cu oxide in the range of 0.25-2.50 wt.%, wherein the conductor part including Cu as a principal component and the magnetic material ceramic are made to be simultaneously fired in an atmosphere having an oxygen partial pressure of 1.0×100-1.0×10-3 Pa, and the conductor part is made by sintering conductive powder having a weight increase ratio before and after debinding processes of 15% or less before firing. The conductive powder, for example, has a surface of Cu-Ni covered with a glass material.
