Abstract: The present invention relates to laminated ceramic electronic components including a ceramic main body; first and second inner electrodes facing each other across a dielectric layer in the ceramic main body; and first and second outer electrodes electrically connected to the first and second inner electrodes. When the dielectric layer is divided into three areas in the thickness direction of the ceramic main body, the average diameters of dielectric grains in a center area and upper and lower areas among the three areas are different from each other. Moreover, the thickness of the dielectric layer is T1, and the thickness of the center area is individually T2. The thickness of the upper and lower areas which are adjacent to the first and second inner electrodes is T3 and T4. The laminated ceramic electronic components are satisfied with T2 >= 0.45T1 and T3 + T4
