Glass plate, vehicle window glass, and laminated glass

The present invention relates to a glass plate having a first surface and a second surface opposite to the first surface, in which no crack is generated when a Vickers indenter indentation test is performed on the first surface or the second surface under 5 [N] force conditions, or c/l < 0.50, where [mm] is the average length of the first surface or the second surface of the generated crack in plan view, and l [mm] is the average length of half of the diagonal line of the indentation; the fracture toughness value KIC, the crack length a, the Young's modulus E, the average thermal expansion coefficient alpha at 20-300 DEG C, and the temperature difference [Delta] T between the temperature TS1 on the first surface side and the temperature TS2 on the second surface side satisfy a certain relationship. 本发明涉及一种玻璃板，所述玻璃板具有第一面和与所述第一面相反的第二面，其中，在对所述第一面或所述第二面进行5[N]的力的条件下的维氏压头压痕试验时不产生裂纹，或者在将产生的裂纹的所述第一面或所述第二面的俯视下的平均长度设为[mm]、将压痕的对角线的一半的平均长度设为l[mm]时，c/l＜0.50，断裂韧性值KIC、裂纹的长度a、杨氏模量E、20℃～300℃下的平均热膨胀系数α、以及所述第一面侧的温度TS1与所述第二面侧的温度
