    • A multilayer ceramic condenser includes a multilayer main body, a first outer electrode, a second outer electrode, a first side part and a second side part. The multilayer main body has a first side, a second side, a third side and a fourth side. The multilayer main body includes a plurality of inner electrodes and a dielectric layer between the inner electrodes. The dielectric layer is formed by a first ceramic dielectric powder. The first side part and the second side part are formed on the second side and the fourth side of the multilayer main body, and formed by a second ceramic dielectric powder having a smaller particle diameter than the first ceramic dielectric powder. A mean grain size of the first side part or the second side part is similar to or smaller than that of the dielectric layer of the multilayer main body.
