Glass plate and method for manufacturing the glass plate

A glass plate comprising:

• two main flat surfaces;
• a side surface adjacent to the two main flat surfaces, and
• a chemically strengthened layer in at least one of the two main flat surfaces,
• wherein at least one edge part of the side surface includes a chamfered part in a thickness direction of the glass plate,
• wherein the side surface includes a predetermined portion,
• wherein the glass plate has a property such that an etched surface of the predetermined portion includes no pit having a depth greater than or equal to 1 μm when the predetermined portion is etched with a depth of 10 μm and a depth of a pit in the etched surface of the predetermined portion is measured, the pit has no microscratch that is a source of breaking,
• wherein the predetermined portion is a portion of the side surface in which a distance from one of the two main flat surfaces adjacent to the chamfered part in the thickness direction of the glass plate is less than or equal to ⅕ of the thickness of the glass plate, and
• wherein a flexural strength of the glass plate is greater than or equal to 300 MPa.
