A Ni—Zn—Cu ferrite material having excellent DC bias characteristics is provided by adding zinc silicate thereto. The above problem can be solved by Ni—Zn—Cu ferrite particles which comprise a spinel-type ferrite and zinc silicate, which have a composition comprising 36.0 to 48.5 mol % of Fe2O3, 7.0 to 38 mol % of NiO, 4.5 to 40 mol % of ZnO, 5.0 to 17 mol % of CuO and 1.0 to 8.0 mol % of SiO2, all amounts being calculated in terms of the respective oxides, and which have a ratio of an X-ray diffraction intensity from a 113 plane of the zinc silicate to an X-ray diffraction intensity from a 311 plane of the spinel-type ferrite is 0.01 to 0.12; a green sheet obtained by forming a material comprising the Ni—Zn—Cu ferrite particles into a film; and a Ni—Zn—Cu ferrite sintered ceramics.
