DIELECTRIC THIN FILM, CAPACITOR ELEMENT, AND ELECTRONIC COMPONENT
A dielectric thin film with high relative permittivity and high insulation can establish the amount of nitrogen in a metal oxynitride to be low. A dielectric thin film, wherein the dielectric composition is a metal oxynitride solid solution including Ma and Mb: a composition represented by the chemical formula MazMbOxNy (Ma is one element selected from Sr, Ba, Ca, La, Ce, Pr, Nd, and Na, Mb is one element selected from Ta, Nb, Ti and W, O is oxygen, and N is nitrogen); when a is the ionic valence exhibited when Ma occupies an A site in the perovskite structure and b is the ionic valence exhibited when Mb occupies a B site in the perovskite structure, a and b are 6.7≤a+b≤7.3, and x, y and z are 0.8≤z≤1.2, 2.450≤x≤3.493, and 0.005≤y≤0.700.
