A ceramic powder that contains, as a main composition, barium titanate powder having a perovskite structure with an average particle size (median size) of 200 nm or smaller as measured by SEM observation, wherein the 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. The ceramic powder is particularly useful in the formation of thin dielectric layers of 1 mum or less and can be used to manufacture MLCCs having both desired capacity and longevity traits.
