PROBLEM TO BE SOLVED: To provide an excellent glass plate in which an alkali metal scarcely diffuses onto a surface of the glass plate, and with which degradation of characteristics of a transparent conductive oxide film is suppressed.SOLUTION: When an average value of hydrogen concentration at a region with a depth of 0.5-1.5 μm from a surface of a glass plate is denoted by surface layer hydrogen concentration, and hydrogen concentration at a region with a depth of 0.5-1.5 μm from a surface of a glass plate of which the depth region with a depth of 100 μm from the surface of the before-mentioned glass plate has been removed is denoted by internal hydrogen concentration, a glass plate has a value represented by ((surface layer hydrogen concentration)/(internal hydrogen concentration)) of 0.80 or less. When the thickness of the glass plate is 0.2 mm or less, however, hydrogen concentration at a region with a depth of 0.5-1.5 μm from a surface of a glass plate of which the depth region with a depth being half o
