Abstract
A multi-layered ceramic electronic component has a ceramic body including a dielectric layer and an internal electrode, and an external electrode formed outside of the ceramic body and electrically connected to the internal electrode. The internal electrode includes a conductive metal and a fiber-shaped ceramic additive. For example, the fiber-shaped ceramic additive can include barium titanate (BaTiO3) and, optionally, dysprosium (Dy) and/or barium (Ba). The fiber-shaped ceramic additive may have a diameter of 10 to 200 nm, and a ratio of length to diameter of 10 to 100.
