摘要：
It is an object of the present invention to provide a new method for reducing the diameter of a bubble existing in a glass plate. Specifically, the present invention provides a method for reducing the diameter of a bubble existing in a glass plate, which comprises irradiating the vicinity of the bubble existing in the glass plate with a light beam emitted from a light source, to raise the temperature of the glass in the vicinity of the bubble to at least the melting point of the glass to reduce the maximum diameter of the bubble.
