METHOD FOR WORKING LAMINATED SHEET, AND WORKED LAMINATED SHEET

摘要

PROBLEM TO BE SOLVED: To provide a method for working a laminated sheet capable of suppressing chipping upon grinding and cracking upon peeling.SOLUTION: Provided is a method for working a laminated sheet 10 having a substrate 12 and a reinforcing sheet 14 coupled with the substrate 12 so as to be peelable. The method for working a laminated sheet comprises a chamfer step of grinding the edge part of the laminated sheet 10 with a grinder 30. The angle &thetas; made by the boundary between the substrate 12 and the reinforcing sheet 14 and the ground face obtained by being ground with the grinder 30 in the substrate 12 is wider than 26° and less than 30°.
