It is impossible to obtain a volume resistivity of 10"Ω・1 or less unless a conductive filler of a larger amount is added to the thermoplastic resin. This results in the disadvantage that the physical properties inherent to the plastic resin are significantly reduced.

った。When adding a fibrous conductive filler to obtain a conductive resin composition, the fiber thickness should be thinner and the fiber length longer; that is, if the added amount is the same, the aspect ratio (length divided by thickness [
) is known to have better conductivity, but as the thickness of the fiber becomes thinner and the length becomes longer, fiber balls are more likely to form and the fiber becomes bulkier, making it difficult to mix wires into thermoplastic resin. In addition, even if mixed wires can be mixed, it takes a long time, and depending on the wire crossing method, the fibers may break or break, leading to a decrease in conductivity.
