PROBLEM TO BE SOLVED: To provide a panel unit capable of reducing differences in color even when there is a slight difference of colors among plural extrusion materials disposed being aligned with each other.SOLUTION: Plural extrusion materials 1, 1 are disposed being aligned with each other in a direction perpendicular to an extrusion direction. The extrusion materials 1, 1 are formed with an irregular pattern 2 in which a protrusion part 3 and concave part 4 are continuously formed on the surface. In the irregular pattern 2, the depth d is uniform, the pitch P and the inclination angle θ are set randomly.SELECTED DRAWING: Figure 1 |
