Abstract: A dielectric compound for a multilayer ceramic condenser having a low sintering temperature and a high dielectric constant includes a base material of (BaxCa1−x)m(TiyZr1−y)O3 (where 0.7≦x≦1, 0.75≦y≦0.9, 0.998≦m≦1.006), an additive including MnO2 of less than 0.8 weight %, Y2O3 of less than 0.8 weight %, V2O5 of 0˜0.1 weight %, and a sintering aid of zLi2O−2(1−z)SiO2 (0.2≦z≦0.9) of less than 1.0 weight %. The weight % is a ratio relating to a weight of base material of the dielectric compound.
