Abstract

A technical object of the present invention is to devise a glass sheet that facilitates position alignment with a substrate to be processed and is less liable to be broken during conveyance, or processing treatment of the substrate to be processed, to thereby contribute to an increase in density of a semiconductor package. In order to achieve the technical object, the glass sheet of the present invention includes, in a contour thereof: a contour portion; and a position alignment portion, in which all or part of an end edge region of the position alignment portion where a surface thereof and an end surface thereof intersect is chamfered.
