Ceramic electronic component
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.
1. A ceramic electronic component comprising:
a ceramic body including a first principal surface and a second principal surface opposed to each other, a first lateral surface and a second lateral surface opposed to each other, and a first end surface and a second end surface opposed to each other, the second principal surface being located at to a mounting surface side of the ceramic body;
a first external electrode located on the first end surface side of the ceramic body and disposed at least on the second principal surface; and
a second external electrode located on the second end surface side of the ceramic body and disposed at least on the second principal surface; wherein
the first external electrode and the second external electrode are disposed on the second principal surface so as to face each other with a predetermined gap region therebetween;
the first external electrode and the second external electrode each include a base layer and a Cu plating layer which covers the base layer and which includes at least one layer; and
in each of the first external electrode and the second external electrode, 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 the 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.
