Therefore, the amount of the antistatic agent per area can be reduced, the contamination of the antistatic agent by bleeding can be prevented, and the conductive layer such as carbon and the short fibers are worn away because the conductive layer is not exposed on the surface. And no airborne pollution. Also, since the conduction distance from the front and back layers of the antistatic to the conductive intermediate layer is shortened, the chargeability is excellent, and furthermore, since the conductive layer having a uniform thickness is laminated between the antistatic layers on both the front and back, It is a conductive sheet of an excellent structure with the same electrical performance from the back side, and it can be arbitrarily colored and has excellent design, such as a semiconductor manufacturing plant, precision machine manufacturing plant, electric component manufacturing plant.
