There is provided a multilayer ceramic electronic component, including: a ceramic element having a plurality of dielectric layers laminated therein; and first and second internal electrodes formed within the ceramic element, wherein the first and second internal electrodes include 80 to 99.9 wt % of copper (Cu) and 0.1 to 20 wt % of nickel (Ni), and a frequency therefor is 1000 MHz or less. The multilayer ceramic electronic component, by adding a very small amount of nickel (Ni) into the copper (Cu), enables a resitance rate (rho) of internal electrodes to change, thereby realizing an equivalent series resistance (ESR) within an intermediate range between the ESR in the case of internal electrodes using palladium and the ESR in the case of internal electrodes using copper, and widens a range of choice in quality factor (Q) as compared with multilayer ceramic electronic components having the same capacitance.
