Abstract: When fixing a glass layer 3 to a glass member 4 by irradiation with laser light employing a one portion 31 of the glass layer 3 as start and end points, the glass layer 3 is cut at the one portion 31. In the glass layer 3, the one portion 31 is made thicker than a main portion 32, whereby end parts 3a, 3b rise fully. Melting the end parts 3a, 3b by irradiation with laser light L2 for a preliminary stage for final firing while pressing them toward the glass member 4 reliably buries a gap G and homogenizes the thickness of the glass layer 3. Thus constructed glass layer 3 is irradiated with the laser light L2 for final firing, so as to fuse the glass members 4, 5 to each other.

Abstract: When fixing a glass layer 3 to a glass member 4 by gasifying a binder and melting a glass fit 2, the glass layer 3 is irradiated with laser light L1 along a region to be fused R from an irradiation start position A in the region to be fused R to the irradiation start position A and then continuously again along an unstable region from the irradiation start position A to a stable region start position B in the region to be fused R, so as to re-melt the glass layer 3 in the unstable region, thereby removing the binder, thus turning the unstable region into a stable region, whereupon the glass layer 3 is fixed to the glass member 4.

Abstract: A glass layer 3 is irradiated with laser light L1 for temporary firing, so that a main portion 32 of the glass layer 3 excluding a one portion 31 thereof and extending like a ring open at the one portion 31 is molten and fixed to a glass member 4. As a consequence, the one portion 31 of the glass layer 3 in which the glass frit 2 is not molten exists between one end 32a and the other end 32b of the glass layer 3 fixed to the glass member 4. Superposing a glass member 5 on the glass member 4 with the glass layer 3 interposed therebetween in this state and irradiating the one portion 31 and main portion 32 of the glass layer 3 with second laser light L2, so as to fuse the glass members 4, 5 to each other, can prevent leaks from occurring in the glass layer 3, thereby making it possible to manufacture a glass fusing structure 1 which requires hermetic fusing.

Abstract: At the time of temporary firing for fixing a glass layer 3 to a glass member 4, the glass layer 3 is irradiated with laser light L2 through the glass member 4 from the glass member 4 side. This fully heats a part of the glass layer 3 on the glass member 4 side and thus can improve the adhesion of the glass layer 3 to the glass member 4. Further, even when irradiated with the laser light L2 at such a laser power as to melt both edge parts of the glass layer 3, the part of the glass layer 3 on the side opposite from the glass member 4 (i.e., the part of the glass layer 3 fused to the other glass member) is prevented from being crystallized by excess heat input, whereby the fusing state of the glass layer 3 with respect to the other glass member can be made uniform.

Abstract: At the time of temporary firing for fixing a glass layer 3 to a glass member 4, the glass layer 3 is irradiated with laser light L2 having a ring-shaped irradiation region. At this time, in a width direction of the glass layer 3, two peaks M in a beam profile of the laser light L2 respectively overlap both edge parts 3b of the glass layer 3. This allows a center part 3a and each of both edge parts 3b of the glass layer 3 to be irradiated for shorter and longer times with a part having a relatively high intensity in the laser light L2, respectively. As a consequence, the amount of heat input by irradiation with the laser light L2 is homogenized between the center part 3a and both edge parts 3b in the glass layer 3, whereby the whole glass layer 3 is molten appropriately.

Abstract: A glass layer 103 containing a binder, a laser-light-absorbing pigment, and a glass frit 102 is irradiated with laser light L2, so as to gasify the binder and melt the glass fit 102, thereby fixing the glass layer 103 to a glass member 104. This allows the glass layer 103 fixed to the glass member 104 to let out the binder and enhance the laser light absorptance, so as to yield a uniform state. As a result, fusing glass members 104, 105 to each other with the glass layer 103 having such a stable state interposed therebetween allows the glass members 104, 105to have a uniform fusing state therebetween.
