A method for manufacturing a disk-shaped glassNsu bstrate is a method for manufacturing a disk-shaped glass substrate for cutting out one or more thin glass substrates. The method for manufacturing a disk-shaped glass substrate includes preparing a disk-shaped glass blank, which is a glass blank having two circular main surfaces (step 51), chamfering an outer edge portionof each of the two main surfaces of the disk-shaped glass blank (stepS2), grinding the two main surfaces of the chamfered disk-shaped glass blank, using a double-side grinding apparatus (step 53), and polishing the two main surfaces of the ground disk-shaped glass blank, using a double-side Bpolishing apparatus(step54).
