Abstract:

A method of glass substrate working, comprising the step of irradiating glass substrate (1) with pulsed laser beams (L) so that the same is focused within the glass substrate (1), thereby creating, around the portion where the pulsed laser beams (L) have been focused, a region of density higher than that of the region not irradiated with the pulsed laser beams (L), and the step of performing a chemical etching of the glass substrate (1) with the use of an etchant so as to cause at least portion of the region of higher density to remain, thereby forming protrudent portion (2) on surface (1a) of the glass substrate (1).
