For example, polymer materials using carbon particles or fibers or metal powders such as copper, silver, gold, etc. as conductive fillers have been proposed. However, carbon particles, carbon fibers, and metal powders such as copper, silver, and gold are all black or have a color unique to metals, and these conductive fillers, except for carbon fibers, are non-reinforcing. It is a filler. In addition, although carbon fiber is a reinforcing conductive filler, it is difficult to make the fiber length uniform, and the aspect ratio is uneven, resulting in poor moldability and poor molding properties. Poor smoothness and polishability.
