PROBLEM TO BE SOLVED: To provide a wet molding method which can produce various small plates in which uneven patterns on the upper surfaces are different eminently by one molding line. SOLUTION: A molding 7 in the shape of a wide belt plate is extrusion- molded from an extrusion molding machine 6. The molding 7 is rolled by a roll 8 with its circumferential surface made an irregular uneven surface to make a belt plate-shaped molding 7', and the molding 7' is cut to make a plain plate 9. The plain plate 9 is punched perpendicularly to the extrusion direction into long, small plates 13a-13d. A punching blade meanders in the longitudinal direction, and its thickness is increased toward the side of its root.
