摘要：
Disclosed is a method for producing a glass substrate, which involves a first polishing step and a second polishing step both for polishing the surface of the glass substrate with a polishing solution containing a polishing agent. The method is characterized by additionally involving a heating step for heating the glass substrate, wherein the heating step is carried out after the first polishing step and before the second polishing step.
