Abstract
A thin-film ceramic capacitor includes: a body in which a plurality of dielectric layers and first and second electrode layers are alternately disposed on a substrate; and first and second electrode pads disposed on an external surface of the body. The dielectric layer contains a mixed phase of a perovskite phase having ferroelectric properties and a pyrochlore phase having paraelectric properties, the pyrochlore phase being disposed on interfaces between the dielectric layers and the first and second electrode layers in lower portions of the dielectric layers.
