Abstract
A glass plate includes a main surface, and a microscopic asperity surface disposed on the main surface, the microscopic asperity surface forming peaks and valleys. When a reference plane is defined as a plane at a center, in a direction of height, of an interval of highest frequency in a histogram of height of shape data of a square region having 2 μm per side in the microscopic asperity surface, the number of peaks that are higher than the reference plane by 20% or more of a maximum height difference in the square region is in a range between 1 or more and 300 or less.
