PROBLEM TO BE SOLVED: To provide a film capable of selectively blocking visible light and transmitting infrared light, which has high withstand voltage even in a thin film, and has a maximum spectral transmittance in a wavelength range of 400 to 650 nm. A film having a value of 50% or less, a minimum spectral transmittance of 20% or more in the wavelength range of 1250 nm to 2500 nm, and an insulation breakdown voltage Pd (Vt) of 90 kV / mm or more.
