摘要： A multilayer ceramic electronic component includes a ceramic body comprising dielectric layers and first and second internal electrodes laminatedly disposed in a third direction with respective dielectric layers interposed therebetween, and first electrode and second external electrodes disposed on both surfaces of the ceramic body in the first direction and electrically connected to the first and second internal electrodes. When an absolute value of a horizontal angle in the second direction of the first internal electrode with respect to the first surface of the ceramic body is referred to a first angle of the internal electrode, a total sum of the first angles is less than 10°.
