PROBLEM TO BE SOLVED: To provide a dielectric film, a film capacitor, and an electric device capable of increasing a relative dielectric constant without reducing a breakdown electric field strength. SOLUTION: A dielectric film including ceramic particles 3 in an organic resin 5 is provided, and the ceramic particles 3 form a crystal lattice formed by three axes a, b and c, and an axial ratio It has two or more kinds of crystal phases 3a and 3b having different c / a. Due to the difference in crystal lattice shape (size), the crystal phases 3a and 3b have different levels of dielectric polarization, so that the ceramic particles 3 have regions having different dielectric constants, thereby reducing the breakdown electric field strength. The relative dielectric constant can be increased without any problems. [Selection] Figure 3 |
