<p><P>PROBLEM TO BE SOLVED: To provide a cutting treatment for a stacked body in which a brittle material substrate and a resin film are stacked, wherein waste such as peeling pieces and cutting pieces is not produced, and the surface of the brittle material substrate is prevented from being damaged. <P>SOLUTION: In a glass substrate 3, from the side face opposite to the side of a resin film face, a crack 5 in the range of 10 to <100% of the thickness of the glass substrate 3 is formed in the almost vertical direction to the glass substrate face. Next, a cutter 2 is brought into press contact in the position at which the crack 5 is elongated in the surface of the resin film 41 or the vicinity thereof, so that the cutter 2 is relatively moved to the stacked body S1, and a notch 6 is made at≥90% to the thickness of the resin film 41 also to the range at which it does not reach the glass substrate 3. In this way, the stacked body S1 is cut. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
