Zusammenfassung:	PURPOSE:To provide an electrical laminate good in insulation resistance after moisture absorption and in smearing resistance and to provide a resin- impregnated base therefor. CONSTITUTION:The resin-impregnated base is one obtained by impregnating a base with an epoxy resin varnish comprising an epoxy resin and a product of the reaction of a hydrogenorganopolysiloxane with a vinylsilane coupling agent and optionally containing a curing accelerator, a solvent, etc., and drying the resulting base. The electrical laminate is one obtained by superposing a necessary number of sheets of the resin-impregnated base, disposing a metal foil on at least one side of the pile, and uniting the laminae.
