Tempered glass plate

A tempered glass plate that is tempered by cooling medium jetted from a plurality of nozzles,

• wherein a thickness of the tempered glass plate is less than or equal to 2.7 mm,
• wherein on a surface of the tempered glass plate, a plurality of stress marks are formed by the cooling medium jetted from the plurality of nozzles,
• wherein a distance between closest stress marks of the plurality of stress marks is less than or equal to 20 mm,
• wherein the surface of the tempered glass plate includes a first virtual circle that is formed by connecting points that are separated from a center of one of the plurality of stress marks by 2.5 mm,
• wherein the tempered glass plate includes a non elastic-wave region that is not affected by an elastic-wave that is generated during fracturing, and
• wherein, during the fracturing, in the non elastic-wave region, an average number of cracks that exist in the first virtual circle is greater than or equal to 3.4.
