Abstract
An object of the present invention is to provide a liquid crystal polymer film having a low dielectric loss tangent. In addition, an object of the present invention is to provide a laminate having the liquid crystal polymer film. The liquid crystal polymer film includes a liquid crystal polymer and a filler, in which, in a case where the liquid crystal polymer film includes one kind of the filler, a dielectric loss tangent of the filler under conditions of 25° C. and a frequency of 10 GHz is 0.0020 or less, and in a case where the liquid crystal polymer film includes two or more kinds of the fillers, a mass average value of dielectric loss tangents of the two or more kinds of the fillers under the conditions of 25° C. and a frequency of 10 GHz is 0.0020 or less, and a ratio of a volume occupied by the filler is 10% by volume or more with respect to a total volume of the liquid crystal polymer film.
