Abstract
A multi-layer ceramic capacitor is made by alternately layering a dielectric layer constituted by a sintered body of a ceramic powder, and an internal electrode layer. The ceramic powder contains, as a main composition, barium titanate powder having a perovskite structure with a median size of 200 nm or smaller as measured by SEM observation, wherein the barium titanate powder is such that the percentage of barium titanate particle having twin defects in the barium titanate powder is less than 10% as measured by TEM observation and that its crystal lattice c/a is 1.0075 or more.
