发明名称 Electronic device, dielectric ceramic composition and the production method
摘要 A production method of a dielectric ceramic composition comprising a main component including at least one selected from BaTiO3, BaCaTiO3, BaTiZrO3 and BaCaTiZrO3, and a fourth subcomponent including rare earth oxide; comprising steps of dividing a material of the main component to a first main component material and a second main component material, obtaining a post-reaction material by making the material of the first main component react in advance with a part of the fourth subcomponent material, and adding the material of the second main component and rest of the fourth subcomponent material into the post-reaction material; wherein, when number of moles of the first main component is n1 and number of moles of the second main component is n2, a ratio is 0.5≦̸n1/(n1+n2)≦̸1: by which preferable characteristic can be obtained even when dielectric layers are made thin.
