Abstract
A transparent substrate includes a first principal surface; a second principal surface as a principal surface on the opposite side of the first principal surface; a lateral surface extending between the first principal surface and the second principal surface; and a first boundary surface disposed between the first principal surface and the lateral surface and having a plurality of concave portions; wherein the first boundary surface is configured such that each of the concave portions has a bottom with a curvature and that the frequency of a maximum curvature is less than 3% in a frequency distribution of the curvatures of the concave portions.
