The invention provides a manufacturing method of conductive cloth. The manufacturing method of the conductive cloth comprises the following steps: performing hot pressing on textile fabrics at hot deformation temperature so as to have fibers flattened as well as have the fibers bonded at cross-lap joints, thereby making bulges on the flattened textile fabrics planar; and then, plating a conductivelayer on surfaces of the flattened textile fabrics. Conductive cloth manufactured by the manufacturing method has a planar conductive layer on the surface; and thus, being applied for textile electrodes, effective contact area of the conductive cloth with the skin is greatly increased under the same pressure, thereby improving signal acquisition capability.
