Abstract
A multilayered capacitor that includes a capacitor body including a dielectric layer and an internal electrode, an external electrode disposed outside the capacitor body, and a thin film disposed on a surface of the capacitor body and including barium zirconium titanate. The barium zirconium titanate includes zirconium in an amount of about 10 parts by mole to about 50 parts by mole based on about 100 parts by mole of titanium.
