摘要： A ceramic inductor component and a composite component are provided having desired properties, superior stability of properties and superior durability. When Ni—Cu—Zn ferrite or Ni—Cu ferrite is used for a magnetic ceramic body constituting an inductor portion, and when the contents of S, Cl and Na contained in the ferrite are set to be in the ranges of about 5 to 150 ppm, about 5 to 150 ppm and about 5 to 100 ppm, respectively, diffusion of an internal conductive metal primarily composed of Ag into the magnetic ceramic body is suppressed, and hence, the degradation of electric properties can be avoided. Accordingly, by facilitating sintering, the insulating resistance of the ceramic is improved, and the durability and reliability of the ceramic inductor component can be improved.

摘要： The present invention provides a system and method for producing a reliable inductor having an internal conductor with a small electric resistance. A metal wire formed in a nonlinear shape is used as the internal conductor. In an exemplary embodiment of the invention, the internal conductor has a coil-like shape with portions adjacent to each other with respect to the axial direction of the coil being positioned in a substantially cylindrical gap formed in the axial direction of the coil. By providing a gap around the internal conductor, stress between the internal conductor and a ceramic material surrounding the conductor can be eliminated. As a result, the characteristic deterioration or crack generation in the inductor chip is eliminated. Moreover, the leakage flux among the coil pitches of the conductor is reduced, thereby improving the characteristics of the inductor.

摘要： A mask is mounted on one surface of a ceramic green sheet which is supported on an X-Y table. The mask is provided with a plurality of through hole transmissive portions. A pulsed laser beam is applied to the mask. The size of the laser beam is sufficiently large to encompass at least several of said through hole transmissive portions. The laser beam passes through the through hole transmissive portions and simultaneously forms a plurality of through holes in the ceramic green sheet. Because the mask is located on (or at least substantially adjacent) the surface of the ceramic green sheet, the size and shape of the through holes will be approximately identical to the size and shape of the through hole transmissive portions, thereby precisely controlling the size and shape of the through holes. The mask can be irradiated while the ceramic green sheet is moving.
