Abstract: A process (I), for producing a pressure-sensitive electroconductive sheet by (A), forming conductive circuits or electrodes in a flexible porous substrate and (B), applying, followed by curing a pressure-sensitive conductive paste to either or both sides of the substrate to form a pressure-sensitive conductive layer; and a process (II) for producing a pressure-sensitive electroconductive sheet by (A), forming conductive circuits or electrodes in a flexible porous subhstrate, (B), subsequently applying, followed by curing, a pressure-sensitive conductive paste to either side of the substrate to form a pressure-sensitive conductive layer, and (C), applying, followed by curing, insulating silicone rubber to the side of the substrate on which the pressure-sensitive conductive layer is not formed to form an insulating silicone rubber layer.
