Abstract
A multilayer ceramic electronic component includes a ceramic body, which includes an electrode-stacking portion in which internal electrodes are stacked, and cover portions facing each other in a first axis direction across the electrode-stacking portion, and external electrodes each including a covering portion that covers the ceramic body from a second axis direction, and an extending portion that extends over the cover portions along the second axis direction. The ceramic body includes crystal grains of ceramic and segregated small grains located between the crystal grains. In a cross section of an end section located between the extending portion of the cover portion and the electrode-stacking portion, the number of the segregated small grains having a grain size of 0.5% or greater and 10% or less of an average grain size of the crystal grains is 40% or greater and 95% or less of the number of the crystal grains.
