A magnetic oxide sintered body made up of 80% or more of Y-type hexagonal ferrite, the magnetic oxide sintered body comprising cobalt oxide, copper oxide, iron oxide, and AO (AO is at least one of BaO or SrO) as a main component. and the mole%, more preferably a main component as an MO (MO is, NiO, ZnO, at least one of MgO) with and a predetermined content of mol%, and bismuth oxide as a subcomponent (Bi 2 O 3), borosilicate glass, borosilicate zinc Since the glass or bismuth glass is formed to contain a predetermined weight%, the magnetic properties are good up to a high frequency band such as several hundred MHz to GHz, and it is possible to use it, and it does not contain more than Y-type hexagonal ferrite. In particular, it is possible to provide a magnetic oxide sintered body and a high frequency circuit component using the same, which can be fired at around 900 ° C. |
