A ceramic electronic component includes 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 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%.

Ceramic electronic component with openings in electrode

A multilayer electronic component includes a body including an active portion inducing dielectric layers and internal electrodes, and upper and lower cover portions, and external electrodes including connection portions and band portions extending onto portions of first and second surfaces of the body, and including an electrode layer and a conductive resin layer. In a cross-section of the body, when a line along which the band portion of the conductive resin layer is in contact with the first surface is d, an area of an isosceles right triangle, in which d is a base and an extension line extending from an end of the electrode layer by a length of d is a height, is K, and a ratio of the area occupied by dummy electrodes in the lower cover portion and the internal electrodes in Kto Kis K, Kis 20% or more.
