Abstract
A method of producing a multilayer ceramic electronic device, having a firing step for firing a pre-firing element body wherein a plurality of dielectric layers and internal electrode layers containing a base metal are alternately arranged, characterized in that the firing step has a temperature raising step for raising a temperature to a firing temperature, and hydrogen is continued to be introduced from a point in time of the temperature raising step. According to the method, it is possible to provide a method of producing a multilayer ceramic electronic device, such as a multilayer ceramic capacitor, wherein shape anisotropy and other structural defaults are hard to occur and electric characteristics are improved while suppressing deterioration thereof even if dielectric layers becomes thinner and stacked more.
