This abstract first appeared for US patent application 18754231 titled 'MULTILAYER CERAMIC CAPACITOR

Original Abstract Submitted

A multilayer ceramic capacitor includes an element body portion including dielectric layers and internal electrode layers including Ni, and external electrodes. In each internal electrode layer, a width of an opposing portion is larger than a width of a lead-out portion. The element body portion includes side margin portions extending from both end portions of the opposing portion to first and second side surfaces, through a central portion in a length direction, and parallel or substantially parallel to a thickness direction and a width direction. A dielectric layer between adjacent internal electrode layers in the thickness direction includes grains including pores. Each of the side margin portions includes a dielectric including grains that do not include pores.
