Abstract:
A monolithic ceramic capacitor includes an element body including a multilayer portion including a plural conductor layers and plural ceramic dielectric layers alternately stacked in a thickness direction. The element body is divided in the thickness direction into thickness-direction first and outer layer portions made of the ceramic dielectric layers, and a thickness-direction inner layer portion including the multilayer portion. The element body bulges to the outer side at a center portion in a length direction, and center portions in the length direction of the plural conductor layers are curved to the outer side. The thickness of a portion of the first outer layer portion adjacent to a first extension portion is larger than the thickness of a center portion thereof, and the thickness of a portion of the second outer layer portion adjacent to a second extension portion is larger than the thickness of a center portion thereof.
