<p>A process of fusing a glass member (104) to a glass member (105) by irradiating a glass layer (203) with a laser beam (L2) along a region (R) to be fused, wherein a crystallized area (108) formed in the glass layer (203) is taken as the irradiation-initiating point and the irradiation-ending point. Since the crystallized area (108) exhibits a laser absorptance lower than that of the glass layer (203), the glass layer (203) is gradually heated when the laser beam (L2) is moved along the region (R) from the irradiation-initiating point, while the glass layer (203) is gradually cooled when the laser beam (L2) is moved along the region (R) to the irradiation-ending point. By virtue of the above constitution, the area including both the initiation point of laser-beam (L2) irradiation and the ending point thereof can be inhibited from suffering residual stress.</p> |
