Abstract
A glass plate includes two main flat surfaces, and a side surface adjacent to the two main flat surfaces. At least one edge part of the side surface includes a chamfered part in a thickness direction of the glass plate. The side surface includes a predetermined portion. In a case where the predetermined portion is etched with a depth of 10 μm, an etched surface of the predetermined portion includes no pit having a depth greater than or equal to 1 μm. 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.
