摘要：
To provide glass to be used for a substrate which is, as a substrate, less susceptible to surface roughening even if subjected to cleaning by means of a strongly acidic solution.Glass for a substrate, which comprises, as represented by mol % based on the following oxides, from 62.5 to 69% of SiO2, from 9 to 15.5% of Al2O3, from 8 to 16 of Li2O, from 0 to 8% of Na2O, from 0 to 7% of K2O and from 0 to 3.5% of ZrO2, provided that SiO2—Al2O3 is at least 53.3%, Li2O+Na2O+K2O is from 17 to 24%, and the total of contents of the above six components is at least 97%.
