PROBLEM TO BE SOLVED: To provide a sintered magnetic oxide which can be baked at 1000 deg.C or below, especially around 900 deg.C, has excellent permeability characteristics in a high-frequency range, high electric resistivity, and low permittivity, and contains Y-type hexagonal ferrite as the main component ferrite, and to provide a high-frequency circuit part using the same. SOLUTION: This magnetic oxide sintered body contains Y-type hexagonal ferrite of 80% or above. The sintered magnetic oxide contains 3 to 15 mol% cobalt oxide in terms of CoO, 5 to 17 mol% copper oxide in terms of CuO, 57 to 61 mol% iron oxide in terms of Fe2 O3 , 0 to 15 wt.% MO (MO is at least one of NiO, ZnO, and MgO, and MO content is above zero), and residual mol% AO (AO is either BaO or SrO) as main components and 0.6 to 7 wt.% borosilicate glass, boron zinc silicate glass, or bismuth glass oxide as an auxiliary component. |
