Abstract
A ceramic electronic component includes a multilayer body in which internal electrodes are stacked in a first axis direction, the multilayer body having side faces perpendicular to a second axis direction that is orthogonal to the first axis direction, ends of the internal electrodes being positioned at the side faces and aligned within a range of 0.5 μm in the second axis direction; and side margin portions covering the side faces, respectively, the side margin portions including a ceramic polycrystal as a main component and glass grains dispersed in the polycrystal, a total volume ratio of the glass grains with respect to the polycrystal being 1% or more and 20% or less, a median diameter of the glass grains is 0.20 μm or more and less than 0.75 μm, and is 90% or more of a median diameter of crystal grains constituting the polycrystal.
