An Origin of ferroelectricity in Perovskite-type oxides is discussed from a viewpoint of relation between lattice dynamics and chemical bonding state, through comprehensive study of a Ca-substitution effect on the ferroelectricity in CdTiO3. The result indicates covalency of constituent elements plays an important role on the ferroelectricity in the perovskite-type oxides.
