摘要：
A method of manufacturing a dielectric ceramic composition comprising at least BaTiO3 as a main component, a second subcomponent having SiO2 as a main component and at least one type selected from MO (note that M is at least one type of element selected from Ba, Ca, Sr and Mg), Li2O and B2O3 and other subcomponents, comprising the steps of mixing in the main component at least part of other subcomponents except for the second subcomponent to prepare a pre-calcination powder, calcining said pre-calcination powder to prepare a calcined powder, and mixing at least said second subcomponent in said calcined powder to obtain a dielectric ceramic composition having ratios of the subcomponents to BaTiO3 as the main component of predetermined molar ratios.
