Provided is a method for manufacturing a glass substrate for an information recording medium, which is advantageous in that oozing of an alkali and deformation of a texture are suppressed. The glass substrate is chemically reinforced, and a texture is formed in the glass substrate, and then treated with a neutral or alkaline aqueous solution. In the texture forming step, the surface of the glass substrate is etched in a depth of 0.5 to 10 nm.
