Abstract

A device 1 for measuring a glass sheet measures the squareness between an end surface Gb and an end surface Gc, which intersect at a corner G1 of a rectangular glass sheet G, wherein the device 1 for measuring a glass sheet is provided with: a table 2 having a mounting section 2x on which the glass sheet G is placed; a first pin 11 which makes contact with the end surface Gc; a second pin 12 which makes contact with the end surface Gb; and a distance meter 13 which measures the actual displacement of the position of a second end surface Gb of the glass sheet G positioned on the mounting section 2x by the first pin 11 and the second pin 12, the displacement being measured relative to a reference position where the second end surface Gb is positioned when the end surface Gb and the end surface Gc form a right angle therebetween.
