Abstract: A porous coating layer formed on a substrate is impregnated, based on a prescribed pattern, with liquid material having a larger cohesion after solidification thereof than that of the coating layer. The liquid material is solidified to form a solidified material. Then, a portion of the coating layer, which has been impregnated with the solidified material is peeled to expose partially the surface of the substrate on the basis of the prescribed pattern, thereby producing the porous coating layer having the prescribed pattern. An electrode plate for a secondary battery with a nonaqueous electrolyte can be produced by utilizing the above-mentioned production process.
