GLASS WELDING METHOD AND GLASS LAYER FIXING METHOD
First Claim
1. A glass fusing method for manufacturing a glass fusing structure by fusing first and second glass members to each other, the method comprising the steps of:
- arranging a glass layer containing a laser-light-absorbing material and a glass powder with a predetermined width on the first glass member along an extending region to be fused;
irradiating the glass layer with first laser light while relatively moving an irradiation region of the first laser light along the region to be fused, so as to melt the glass layer, thereby fixing the glass layer to the first glass member; and
superposing the second glass member on the first glass member having the glass layer fixed thereto with the glass layer interposed therebetween and irradiating the glass layer with second laser light, so as to fuse the first and second glass members to each other;
wherein the glass layer is irradiated with the first laser light through the first glass member from the first glass member side.

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.

5. A glass layer fixing method for manufacturing a glass-layer-fixed member by fixing a glass layer to a first glass member, the method comprising the steps of
arranging the glass layer containing a laser-light-absorbing material and a glass powder with a predetermined width on the first glass member along an extending region to be fused; - and
irradiating the glass layer with first laser light while relatively moving an irradiation region of the first laser light along the region to be fused, so as to melt the glass layer, thereby fixing the glass layer to the first glass member; wherein the glass layer is irradiated with the first laser light through the first glass member from the first glass member side.
