Multilayer ceramic electronic component

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 plurality of internal conductive layers each include a plurality of holes, each having a different shape and a different area equivalent diameter;
• 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 average value of circularity of the plurality of holes in a first population including holes each having the area equivalent diameter D90 or more is about 0.7 or less.
