SOLUTION: A multilayer ceramic electronic component with a dielectric layer and an electrode layer laminated alternately is manufactured by laminating an interior green sheet containing dielectric powder and an electrode precursor layer containing a conductive material alternately to form an interior. Then an exterior green sheet is laminated on the opposite sides of the interior in the laminating direction, they are burnt, and dielectric powder is added to the electrode precursor layer. It is assumed that the mean particle diameter of the dielectric powder contained in the interior green sheet is Ra, and the mean particle diameter of the dielectric powder added to the electrode precursor layer is Rb. Consequently, following relation is set; Rb/Ra≤1/2, and dielectric powder similar to that of the electrode precursor layer is also added to the exterior green sheet. Preferably, the dielectric powder similar to that of the electrode precursor layer is added to the exterior green sheet by 0.1 to 20 mass%.
