Fusion bonding process for glass

Abstract

A part of a glass layerdisposed along a region to be fused R is irradiated with a laser beam L, so as to form the glass layerwith a laser-absorbing parthaving a high laser absorptance. Then, while using the laser-absorbing partas an irradiation initiation position, the region to be fused R is irradiated therealong with a laser beam L, so as to melt the glass layerand fix the glass layeronto a glass member. Since the irradiation initiation position for the laser beam Lhas already become the laser-absorbing part, a stable region where the melting of the glass layeris stable can be formed immediately from the start point for initiating the irradiation with the second laser beam or nearby. The glass memberis fused to a glass memberthrough the glass layerhaving such a stable region formed throughout the region to be fused R, so as to yield a glass fusing structure
