Abstract

The present invention relates to a dielectric ceramic composition, method for preparing the same, and electronic device using the same. According to the present invention, there is provided a dielectric ceramic composition which allows use of a nickel internal electrode, sintering under a reducing atmosphere, and having 1000 or higher dielectric constant while providing excellent dc-bias properties and reliability which is close to paraelectric property. The composition of the present invention can generate high effective capacity under high DC voltage, have strong resistance against electrostatic discharge (ESD) damage, and be used for preparing an electronic device having low acoustic noise.
