PROBLEM TO BE SOLVED: To provide a sintered ferrite material which has a high saturation magnetic flux density and a small temperature coefficient of initial permeability. SOLUTION: In this method, a sintered ferrite material is manufactured by using Fe2 O3 , NiO, ZiO and CuO as principal components, and adding at least one of PbO and HBO3 at 0.00211-0.00528mol% or Bi2 O3 at 0.00101-0.00253mol%, and at least one of SiO2 , Cr2 O3 , Al2 O3 , SnO2 and WO3 at 0.00392-0.00982mol, to the principal components at 100mol%. |
