To provide a glass substrate which increases the impact resistance at an end part against collision from an oblique direction and improves the appearance of a printing layer or a functional layer.SOLUTION: Disclosed is a glass substrate which includes: a pair of main surfaces; an end surface arranged along the direction orthogonal to the pair of main surfaces; and a connection surface arranged between the main surface and the end surface. The connection surface has a plurality of pores, and in the pores, a difference between a 50% particle diameter at a portion 20 μm away from the main surface and a 50% particle diameter at a portion 20 μm away from the end surface is 10 μm or less.SELECTED DRAWING: Figure 3 【課題】斜め方向からの衝突に対する端部耐衝撃性を高め、かつ印刷層または機能層の外観も向上するガラス基体を提供する。【解決手段】一対の主面、上記一対の主面に対して直交する方向に沿って配置された端面、及び上記主面と上記端面との間に配置された接続面を有するガラス基体であって、上記接続面は複数のポアを有し、上記ポアは、上記主面より２０μｍ離れた部分での５０％粒子径と上記端面より２０μｍ離れた部分での５０％粒子径の差が１０μｍ以下であるガラス基体。【選択図】図３
