    • A ceramic electronic component includes a ceramic body, a first external electrode, and a second external electrode. The first and second external electrodes are disposed on a principal surface, which is directed to the mounting surface side, of the ceramic body so as to face each other with a predetermined gap region therebetween. The external electrodes each include a base layer and a Cu plating layer which covers the base layer. In each of the first and second external electrodes, an expression 0.1≦t/d≦0.5 is satisfied, where t is a thickness of the Cu plating layer at an end of the base layer on a gap region side, and d is a distance from the end of the base layer on the gap region side to an end of the Cu plating layer on the gap region side.

    • In a ceramic electronic component having a thin structure, the occurrence of cracks due to stress applied when the ceramic component is being mounted or in a mounted state are prevented. Each of first and second external terminal electrodes has a substantially rectangular region on a principal surface of a ceramic element body, the principal surface being directed to the mounting surface side. An end of the first external terminal electrode, which is arranged in contact with a gap region, and an end of the second external terminal electrode, which is positioned in contact with the gap region, each preferably have a concave-convex shape on the principal surface.
