Patent abstract
A sintered ceramic has a porosity of greater than about 30 percent and less than about 80 percent by volume. Pores are filled with an epoxy resin. A filling factor of the epoxy resin is about 40 percent by volume or more. A monolithic ceramic electronic component having an inner electrode, for example, a chip inductor is manufactured with such a porous sintered ceramic. When a direct current is superimposed, the resulting monolithic ceramic electronic component has a substantially unchanged self-resonant frequency and also has a rate of decrease in impedance of about 50 percent or less at 100 MHz.
