A multilayer ferrite component is produced with powder for magnetic ferrite, characterized by having the composition of Fe2O3: 40 to 51 mol %, CuO: 7 to 30 mol %, ZnO: 0.5 to 35 mol % and MgO: 5 to 35 mol %, in which a peak of particle size distribution positions in range of 0.3 to 1.2 mum. This MgCuZn ferrite uses such powders of less deterioration in a permeability mu and a peak position of particle size distribution in range of 0.3 to 1.2 mum, thereby enabling a co-firing together with Ag or Ag alloys. It is provided a magnetic ferrite of less deterioration in a magnetic characteristic, in particular a permeability mu against stress and enabling to be sintered at low temperature sintering, that is, below the melting points of Ag or Ag alloys used as electrode materials.
