Abstract
A glass substrate includes a pair of main surfaces including a first main surface and a second main surface opposed to the first main surface; an edge surface arranged along a direction orthogonal to the pair of main surfaces; and a connecting surface arranged between the first main surface and the edge surface. The connecting surface has a plurality of pores. A difference between a 50% particle diameter of the pores in a portion 20 μm distant from the first main surface and a 50% particle diameter in a portion 20 μm distant from the edge surface is 10 μm or less.
