Abstract
A method for processing a brittle plate includes a breaking step in which a pressing member for pressing a surface of the brittle plate and a support member for supporting a back face of the brittle plate are used to bend and deform the brittle plate and break the brittle plate along a score line formed on the surface of the brittle plate. The support member includes a flat portion that is arranged flat against one portion of the brittle plate to support the brittle plate, and a regulating portion that regulates a bending deformation shape of the brittle plate when the pressing member is pressed against a predetermined position of a remaining portion of the brittle plate. The breaking step includes breaking the brittle plate along the score line that is within the remaining portion of the brittle plate.
