The present invention provides a transparent conductor comprising a successive lamination of a support, a conductive particle layer containing a conductive particle and a first binder, and a conductive film layer containing a bead and a second binder; wherein a surface of the conductive film layer opposite from the conductive particle layer is rough. The invention also provides an abrasive product made by the method. The first slew rate control circuit is coupled between the first output transistor and a first power supply terminal.
