ABSTRACT:
The object is to prevent the degradation of an attraction layer in an electrostatic attraction board system when objects are attracted for a long time. The electrostatic attraction board system comprises a coating layer disposed over the surface of the attraction layer formed of a layered dielectric substance and a pair of positive
egative comb-teeth like electrodes disposed in a laminating structure on the back face of the attraction layer. Objects such as paper sheets are attracted and held on the surface of the coating layer by coulomb force, The coating layer is formed of a plastic material such as biaxial drawn polyester having a low oxygen permeability and a low vapor permeability, and has a volume resistivity of 10.sup.10 .OMEGA.cm or more and thickness of 5 to 50.mu..
