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 on the first glass member along a region to be fused extending like a closed ring;
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 a main portion of the glass layer extending like a ring open at a one portion of the glass layer, thereby fixing the main portion of the glass layer to the first glass member; and
superposing the second glass member on the first glass member having the main portion of 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
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.

9. 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 on the first glass member along a region to be fused extending like a closed ring; 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 a main portion of the glass layer extending like a ring open at a one portion of the glass layer, thereby fixing the main portion of the glass layer to the first glass member.
