<P>PROBLEM TO BE SOLVED: To provide a compound sintered compact of a magnetic body and a dielectric, which has a high relative permeability and a high relative dielectric constant at 100 MHz to 1 Hz, and to provide an LC composite electronic component using the same. <P>SOLUTION: The compound sintered compact of the magnetic body and dielectric includes: as main crystal, a Y type hexagonal Ba ferrite containing 3.3 to 7.5 atom% Cu based on the total amount of Ba, Fe, Co, Zn, and Cu; and as other crystal, a Zn spinel type ferrite and SrTiC<SB>3</SB>containing 8.7 to 16.3 atom% Cu based on the total amount of Fe, Co, Zn, and Cu. The compound sintered compact of the magnetic body and dielectric is characterized in that the rate of the total amount of the Y type hexagonal Ba ferrite and Zn spinel type ferrite in the crystal of the compound sintered compact is 63 to 77, and also characterized by containing the Zn spinel type ferrite by 15 to 31 mass% and the SiTiO<SB>3</SB>by 10 to 17 mass%. <P>COPYRIGHT: (C)2010,JPO&INPIT |
