PROBLEM TO BE SOLVED: To provide an extremely rational product; and to perform stock control, by remarkably reducing cost required for a manufacturing facility more than when wholly separately press-molding scaffolding boards of two standards, by extremely rationally manufacturing the scaffolding boards of both standards, by coping with any of manufacture of the scaffolding board of a wide standard and manufacture of the scaffolding board of a narrow standard. SOLUTION: This scaffolding board is constituted by being dividedly molded by two side part floorboards 1 and 2 formed by being set in a dimension for forming a lateral width of 500 mm being a specified dimension of the narrow scaffolding board by juxtaposing the floorboards, and a central part floorboard 3 formed by being set in a dimension for forming a lateral width of 580 mm being a specified dimension of the wide scaffolding board in the whole when positioned in a central pard of the side part floorboards 1 and 2.
