A multilayer ceramic electronic component includes a ceramic body including a capacitance formation portion including a dielectric layer and first and second internal electrodes with the dielectric layer interposed therebetween; and first and second external electrodes disposed on the first and second surfaces of the ceramic body, respectively, and including first and second base electrodes connected to the first and second internal electrodes and first and second conductive layers disposed to cover the first and second base electrodes. When a thickness of the first and second conductive layers in a central portion of the first and second surfaces of the ceramic body is ‘a’, and a thickness of the first and second conductive layers at an end of the capacitance formation portion is ‘b’, ‘b/a’ is 0.07 or more.
