发明名称 DIELECTRIC PORCELAIN COMPOSITION AND ELECTRONIC DEVICE
摘要 An object of the invention is to provide a multilayer ceramic capacitor having high dielectric constant, good temperature characteristic, and an improved IR temperature dependency. According to the present invention, a capacitor device body 10, wherein dielectric layers 2 comprising dielectric ceramic composition and internal electrode layers 3 are alternately laminated, characterized in that said dielectric ceramic composition comprises a plural number of crystal particles 2a wherein said crystal particles 2a form Ca dispersing area 25a wherein at least said Ca is dispersed from the surface to inside of crystal particles, and when considering crystal particles 2a having an average particle diameter of D50, an average depth T of said Ca dispersing area is controlled within a range of 10 to 30% with respect to the average particle diameter of D50, is provided (Fig. 2).
