Abstract:
A method of producing a dielectric ceramic composition containing a component expressed by a composition formula of (AO)m.BO2, wherein the element A in said composition formula is at least one element selected from Sr, Ca and Ba, and the element B in said composition formula is at least one selected from Ti and Zr, including the steps of:preparing a material expressed by a composition formula of (AO)mâ€².BO2, wherein a mole ratio mâ€² in said composition formula fulfills mâ€²obtaining the component material by adding a substance containing said element A to the material and adjusting said mole ratio mâ€² to mâ€²=m; and producing said dielectric ceramic composition by firing composition materials including the component material.
