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 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 particles having twin defects in the barium titanate powder is 13% or more as measured by TEM observation and that its crystal lattice c/a is 1.0080 or more. The ceramic powder has a wide range of optimum sintering temperatures and thus offers excellent productivity and is particularly useful in the formation of thin dielectric layers of 1 μm or less. |
