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 binder, a laser-light-absorbing material, and a glass powder on the first glass member along a ring-shaped region to be fused;
irradiating the glass layer with first laser light along the region to be fused from an irradiation start position in the region to be fused to the irradiation start position and then continuously again along a predetermined region from the irradiation start position in the region to be fused, so as to gasify the binder and melt the glass powder, 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.

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.

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 a glass layer containing a binder, a laser-light-absorbing material, and a glass powder on the first glass member along a ring-shaped region to be fused; - and
irradiating the glass layer with first laser light along the region to be fused from an irradiation start position in the region to be fused to the irradiation start position and then continuously again along a predetermined region from the irradiation start position in the region to be fused, so as to gasify the binder and melt the glass powder, thereby fixing the glass layer to the first glass member.
