Claim 18:
19. A method of manufacturing a ceramic electronic component, the method comprising:
forming an element body that includes a dielectric and internal electrodes, the element body having an upper surface, a lower surface, and side surfaces;
applying a base material for base layers of external electrodes onto the lower surface and the side surfaces of the element body;
sintering the base material to form the base layers of external electrodes, the base layer of each of the external electrodes having a lower part formed on the lower surface of the element body and a side part formed on one of the side surfaces of the element body and being electrically connected to one or more of the internal electrodes;
thereafter, forming an insulating layer on the upper surface of the element body and on respective portions of the base layers that are respectively on the side surfaces of the element body; and
forming plating layers on the base layers, respectively, each of the plating layers being formed on the lower part and portion of the side part of the corresponding base layer, such that a boundary between the insulating layer and the plating layer of each of the external electrodes is positioned at a level between the upper surface and the lower surface of the element body and is distant at least 10 micrometers from the upper surface.
