Abstract
A dielectric film includes a main component of a complex oxide represented by a general formula of (SrCa)TiO. 0.40≤x≤0.90 and 0.90≤y≤1.10 are satisfied. A ratio of a diffraction peak intensity on (1, 1, 2) plane of the complex oxide to a diffraction peak intensity on (0, 0, 4) plane of the complex oxide in an X-ray diffraction chart of the dielectric film is 3.00 or more. Instead, a ratio of an intensity of a diffraction peak appearing at a diffraction angle 2θ of 32° or more and 34° or less to an intensity of a diffraction peak appearing at a diffraction angle 2θ of 46° or more and 48° or less in an X-ray diffraction chart of the dielectric film obtained by an X-ray diffraction measurement with Cu-Kα ray as an X-ray source is 3.00 or more.
