In forming a metal oxide dielectric film of perovskite type for capacitor, an array of lower electrodes and a crystallization-assisting conductive film are simultaneously formed. The crystallization-assisting conductive film is formed outside the lower electrode array, at a distance of about 10 mum or less from the outermost lower electrodes, in a width of 20 mum or more. Then, a metal oxide dielectric film is formed thereon. Since the crystallization-assisting conductive film assists the crystallization of metal oxide dielectric film, capacitor elements which are superior in properties and reliability even when the capacitor elements are produced in a fine structure is obtained.
