Provided is a method for production of a glass substrate, whereby the eroded length of an electrode in the dissolution bath during operations can be correctly estimated, and the operating interval extended. The method includes a step of calculating the amount of tin oxide eluted into the glass substrate from the electrode, on the basis of difference between the weight of the tin oxide contained in the glass substrate and the weight of the tin oxide supplied to the glass substrate from the glass starting material; a step of calculating the eroded length of the electrode on the basis of the eluted weight; and a step of pushing the electrode to a predetermined position towards the direction of the molten glass, on the basis of the eroded length. |
