Abstract:
1. A multi-layer ceramic capacitor having a substantially hexahedral capacitor main body wherein: the ceramic dielectric layers comprise barium titanate; the internal electrode layers are laminated alternately; and the internal electrode layers are formed such that they are exposed at the ends thereof alternately to end faces opposed to each other, and a pair of external electrodes formed at the end faces where the ends of the internal electrode layers of the capacitor main body are exposed and connected electrically with the internal electrode layers; wherein the ceramic dielectric layer contains an Si oxide being converted as SiO the ceramic dielectric layer has crystal grains, crystal grain boundaries present between the crystal grains and grain boundary triple points; and B/A is 0.5 or less, wherein the amount (mol) of an Si oxide being converted as SiO
