1. A ceramic electronic component comprising:
a ceramic body having opposed end portions; and
outer electrodes each respectively covering one of the opposed end portions of the ceramic body, each outer electrode including:
an end-surface portion;
a side-surface turnover portion; and
a glass layer in contact with the ceramic body in a region within at least 5 μm in linear distance from a covering end portion of the side-surface turnover portion and extending in a direction toward the end-surface portion, and which contains, at least, Si, wherein
the glass layer is non-conductive;
an average thickness of the glass layer is 3 μm to 10 μm; and
a content of the Si in the glass layer is 11% to 40% by weight.
