Abstract
A multilayer ceramic electronic component includes a ceramic body, and first and second external electrodes facing each other in a second axis direction. The ceramic body includes internal electrodes, and has a rectangular parallelepiped shape having first and second end surfaces, and four connection surfaces each connecting the first and second end surfaces. The connection surface has an uneven region located between the first and second external electrodes. The uneven region includes recess portions formed along an extension direction intersecting the second axis direction and arranged along an arrangement direction orthogonal to a depth direction and the extension direction, and a protrusion portion located between the recess portions. A depth of the recess portion in the depth direction is 0.1 μm or greater and less than 2.5 μm. An arrangement pitch of the recess portions along the arrangement direction is 1 μm or greater and 80 μm or less.
