Manufacturing method of multilayer ceramic electronic device

Abstract

A manufacturing method of a multilayer ceramic electronic device includes: forming each of stack units by forming each of internal electrode patterns on each of dielectric green sheets, the each of internal electrode patterns including Ni, Sn and Au; forming a multilayer structure by stacking the each of stack units; and firing the multilayer structure, whereby each internal electrode layer is formed from the each of internal electrode patterns and each dielectric layer is formed from the each of the dielectric green sheets wherein, in the each internal electrode layer, an Au concentration near each interface between the each internal electrode layer and the each dielectric layer is larger than an Au concentration in each center portion in a thickness direction.
