摘要： When an external terminal electrode of a ceramic electronic component such as a laminated ceramic capacitor is formed by plating, plating growth may be also caused even in an undesired location. The ceramic surface provided by a component main body is configured to include a high plating growth region of, for example, a barium titanate based ceramic, which exhibits relatively high plating growth, and a low plating growth region of, for example, a calcium zirconate based ceramic, which exhibits relatively low plating growth. The plating film constituting a first layer to define a base for an external terminal electrode is formed in such a way that the growth of a plated deposit deposited with conductive surfaces provided by exposed ends of internal electrodes as starting points is limited so as not to cross over a boundary between the high plating growth region and the low plating growth region toward the low plating growth region.
