Abstract
An embodiment of the present invention relates to a film including a layer A, and a layer B provided on at least one surface of the layer A, in which a dielectric loss tangent of the film is 0.010 or less, and a ratio of an absorbance of the layer B at a wavelength of 355 nm to an absorbance of the layer A at a wavelength of 355 nm is 0.45 or more and 1.00 or less, and a laminate including a film having a layer A and a layer B, and a metal layer or a metal wire on a B layer side of the film, in which a dielectric loss tangent of the film is 0.010 or less, and a ratio of an absorbance of the layer B at a wavelength of 355 nm to an absorbance of the layer A at a wavelength of 355 nm is 0.45 or more and 1.00 or less.
