摘要： Provided is an anti-reflection glass substrate comprising an anti-reflection layer having a predetermined thickness from the surface, the anti-reflection glass substrate being characterized in that the anti-reflection layer has at least two layers of a first layer and a second layer successively provided in the depth direction from the surface, each of the first layer and the second layer has a plurality of pores, and the porosity of the first layer is smaller than the porosity of the second layer. In addition, provided is a method for manufacturing an anti-reflection glass substrate, the method successively comprising a step of etching a glass substrate using a first etching liquid and a step of etching the glass substrate using a second etching liquid, the method being characterized in that the molarity of multivalent metal ions of the first etching liquid is larger than the molarity of multivalent metal ions of the second etching liquid. Provided is a method for manufacturing an anti-reflection glass substrate, the method successively comprising a step of etching a glass substrate using a first etching liquid and a step of etching the glass substrate using a second etching liquid, the method being characterized in that the molarity of hydroxides and fluorides of the first etching liquid is smaller than the molarity of hydroxides and fluorides of the second etching liquid.
