A panel of this type can be manufactured by extruding an aluminum billet using an extruder equipped with a die having a molding gap corresponding to its cross-sectional shape. Since this panel is used by laying and arranging a large number of the panels adjacent to the floor surface, it is desired that the panel is formed as wide as possible. However, when it is manufactured by extrusion, its width dimension is limited by the diameter of the die. For example, a wide extruded plate material having a width of about 500 mm or 600 mm or more cannot be manufactured.
