A method of producing a liquid crystal polymer film, the method comprising:
- dispersing a liquid crystal polymer powder and an inorganic filler in a dispersing medium to obtain a mixture;
- drying the mixture to form a mixture mat;
- and
- heat-pressing the mixture mat to obtain the liquid crystal polymer film having a relative permittivity of 5 to 10, and wherein an average value of distances between barycentric coordinates of particles of the inorganic filler in the liquid crystal polymer film is 0.5 μm to 2.0 μm.
