Patent abstract
There is provided a Mn—Zn based ferrite member excellent in mass productivity, high in withstand voltage, low in loss and excellent in direct current superposition property. The Mn—Zn based ferrite member is provided with a surface layer portion having the properties that ρ5 defined in the specification satisfies the relation that ρ5≧103 Ωm and ρ50 defined in the specification satisfies the relation that ρ50≦102 Ωm.ρ5: (R0−R1)S/L5 (Ωm)ρ50: (R2−R3)S/L50 (Ωm)
