1. A ceramic electronic component comprising:
a body including a dielectric layer and a plurality of internal electrodes stacked in a first direction with the dielectric layer interposed therebetween and including first and second surfaces opposing each other in the first direction and side surfaces connected to the first and second surfaces;
an external electrode disposed on one of the side surfaces of the body and extending onto a portion of the first surface of the body; and
an insulating layer covering a surface of the external electrode and including a plurality of openings exposing the external electrode,
wherein a ratio of an area of the plurality of openings to an area of the surface of the external electrode covered by the insulating layer is 20% to 70%,
the external electrode includes a first electrode layer disposed on the body, a second electrode layer disposed on the first electrode layer, and a third electrode layer disposed on the second electrode layer,
the insulating layer is disposed on the first surface of the body and an outer surface of the third electrode layer, such that the plurality of openings of the insulating layer expose the third electrode layer, and
at least two openings among the plurality of openings have different sizes from each other.
