Abstract: To provide an ion-exchange membrane that, when being used in a redox flow battery, provides excellent current efficiency and can suppress reduction in voltage efficiency. The ion-exchange membrane contains a fluorinated polymer having sulfonic acid-type functional groups and is characterized in that the difference (D−Dc) between the distance D between ion clusters measured by the small angle X-ray scattering method, and the diameter Dc of an ion cluster is larger than 0 and at most 0.50 nm.

Abstract: The present invention relates to a film-attached glass substrate, characterized by: being provided with a glass substrate having two primary surfaces each having a compressive stress layer, and a film containing 1 at % or more of K disposed on one of the primary surfaces of the glass substrate; and the ratio of the difference in the amount of K in the compressive stress layer between the primary surfaces, the ratio being represented by formula (1), being −0.027 to 0.027. Formula (1): Ratio of difference in amount of K of compressive stress layer between primary surfaces=(amount of K in first primary surface−amount of K in second primary surface)/[(amount of K in first primary surface+amount of K in second primary surface)/2]
