[Problem] To provide a method for manufacturing glass substrates such that it is possible to obtain multiple glass substrates stably from a large glass matrix on which a strong strengthening treatment has been performed. [Solution] A method for manufacturing glass substrates comprises a first chemical polishing step and a second chemical polishing step. In the first chemical polishing step, a chemical polishing treatment is performed on only the first major surface of a glass matrix (10) by a predetermined amount of single-side polishing. In the second chemical polishing step, a chemical polishing treatment is performed on each of the first major surface and the second major surface. Subsequently, first partitioning grooves (102) formed in the first major surface and second partitioning grooves (104) formed in the second major surface are connected to each other at a position shifted from the center line (110) in the thickness direction of the glass matrix (10) by an amount of shift (114) which corresponds to the amount of single-side polishing. |
