Abstract
The present invention relates to a dielectric element such as a thin-film capacitor including a dielectric film. The dielectric film contains a main component represented by the general formula (BaCa)(TiZr)Owherein 0<x≤0.500, 0<y≤0.350, and 0.900≤z≤0.995. The dielectric film includes a layer containing columnar crystal grains and a layer containing spherical crystal grains, and contains as a sub-component at least one of divalent metal elements and trivalent metal elements.
