Abstract:
A composite sintered body of dielectric substance and magnetic substance comprises a hexagonal Ba ferrite crystal, a perovskite type crystal containing at least one element selected from Ca, Sr, and Ba, and Ti, and Li element, and the relative magnetic permeability is 1.4 or more at 1 GHz. LC composite electronic component comprises the composite sintered body, a condenser circuit formed in the inside or the surface of the composite sintered body, and an inductor circuit formed in the inside or the surface of the composite sintered body.
