2. Description of the Related Art Conventionally, as a method for producing a conductive composite using a polymer, a method has been used in which a certain amount or more of a conductive filler is added to a polymer matrix. However, this method has the drawback that the physical properties of the composite are significantly reduced by the addition of filler, and that the conductivity can only be controlled within the range of the filler used. Furthermore, when used in electronics-related applications, it is difficult to form complex patterns on the film surface.
Additionally, there was a risk that the filler would fall off.
