Multilayer ceramic electronic component including internal conductive layer including a plurality of holes

A multilayer ceramic electronic component comprising:

• a multilayer body including a plurality of stacked ceramic layers, a plurality of internal conductive layers stacked on the ceramic layers, a first main surface and a second main surface opposing each other in a height direction, a first side surface and a second side surface opposing each other in a width direction perpendicular or substantially perpendicular to the height direction, and a first end surface and a second end surface opposing each other in a length direction perpendicular or substantially perpendicular to the height direction and the width direction;
• and
• external electrodes each connected to the internal conductive layers;
• wherein
• the internal conductive layers each include a plurality of holes each having a different area equivalent diameter;
• the plurality of holes include first holes including ceramic pillars therein and second holes not including ceramic pillars therein, the ceramic pillars connecting ceramic layers on one side and one other side of the internal conductive layers;
• when an area equivalent diameter in which a cumulative value in a cumulative distribution of area equivalent diameters of the plurality of holes existing in each of the internal conductive layers is about 90% is defined as an area equivalent diameter D90, an abundance ratio of the first holes in a first population including holes each having the area equivalent diameter D90 or more is about 14% or more;
• and
• the abundance ratio of the first holes in the first population including holes having the area equivalent diameter D90 or more is higher than an abundance ratio of the first holes in a second population including holes each having an area equivalent diameter smaller than the area equivalent diameter D90.
