PROBLEM TO BE SOLVED: To provide an Mn-Zn-based ferrite material of which the loss in a high frequency area of 1 MHz or higher and near at 100°C is small.;SOLUTION: The Mn-Zn-based ferrite material contains, as main components, 53-56 mol% Fe2O3, 0-7 mol% ZnO, and the residue being MnO and also contains, as accessary components, 0.15-0.65 wt.% Co in terms of CoO, 0.01-0.045 wt.% Si in terms of SiO2, and 0.05-0.40 wt.% Ca in terms of CaCO3. The δ value (the amount of cation defects) in ferrite compositional formula (1) of the Mn-Zn-based ferrite material is 5×10-3≤δ≤19×10-3. Compositional formula (1) is (Zna2+, Tib4+, Mnc2+, Mnd3+, Fee2+, Fef3+, Cog2+, Coh3+)3O4+δ, provided that a+b+c+d+e+f+g+h=3, δ=a+2b+c+(3/2)d+e+(3/2)f+g+(3/2)h-4, and [g:h=1:2].;COPYRIGHT: (C)2007,JPO&INPIT
