PROBLEM TO BE SOLVED: To reduce man-hour for packaging plate-like parts and peeling off protective sheets by a method wherein a protective sheet is stuck to one side of a substrate and dividing incisions are formed at the other side of the substrate. SOLUTION: Since six pieces of mirror 201-206 are connected together in plurality connected plate-like parts 10, the six mirrors can be packaged at once. Therefore, packaging becomes easy, with the time required for packaging shortened, as compared with a way wherein the mirrors are packaged one by one. Only one piece of protective sheet is stuck. The size of the protective sheet 16 for the mirrors becomes six times the one that is separated one after another, but the number of peeling-offs becomes one-sixth and thereby the time can be shortened. With a force working in the direction of opening applied to a substrate 12, incisions 18 split the substrate 12 into six pieces along the five incisions 18. With the mirror 206 pinched and pulled, the mirror 206 is separated from the protective sheet 16. As a part of the protective sheet 16 is pulled, the remaining part of the protective sheet is peeled off.
