Abstract:
1. A laminated ceramic electronic component comprising: a laminated body including a plurality of stacked ceramic layers and internal electrodes formed along specific interfaces between the ceramic layers; and an external electrode on an outer surface of the laminated body electrically connected to specific ones of the internal electrodes, wherein the laminated body is divided into a first grain region in which a ceramic constituting the ceramic layers has a first grain diameter and a second grain region in which the ceramic has a second grain diameter, the first grain diameter being larger than the second grain diameter, the first grain region is located outside the second grain region, and a boundary surface between the first grain region and the second grain region is located inside the outer surface of the laminated body while surrounding a section in which internal electrodes are present in the laminated body, the laminated body has a rectangular parallelepiped shape including a LW surface defined by length-direction dimension L and a width-direction dimension W of the laminated body, a LT surface defined by the length-direction dimension L and a thickness-direction dimension T of the laminated body, and a WT surface defined by the width-direction dimension W and the thickness-direction dimension T of the laminated body, the external electrode is on the WT surface, the boundary surface between the first grain region and the second grain region extends continuously along at least the LW surface and the LT surface, and a D
