Abstract
Provided is a method of manufacturing plate-like members whereby shape defects in the plate-like members can be prevented to increase production yield and a laminate for use in the method of manufacturing plate-like members. A method of manufacturing a plurality of plate-like members by breaking a base materialfor plate-like members into segments includes the steps of: preparing a base materialfor plate-like members having a first principal surfaceand a second principal surfaceopposed to each other; forming a breaking groovein the first principal surfaceof the base materialfor plate-like members; bonding a support filmto the second principal surfaceof the base materialfor plate-like members; bonding an adhesive filmto the first principal surfaceof the base materialfor plate-like members to cover the first principal surfaceof the base material; and breaking the base materialfor plate-like members into segments along the breaking grooveby pressing, through the support filmand with the adhesive filmbonded to the base materialfor plate-like members, a region of the base materialfor plate-like members where the breaking grooveis formed.
