Abstract
A glass layer 103 containing a binder, a laser-light-absorbing pigment, and a glass fit 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, 105 to have a uniform fusing state therebetween.
Claims3
1-2. (canceled)
3:
- A glass layer fixing method for manufacturing a glass-layer-fixed member by fixing a glass layer to a glass member, the method comprising:
- arranging the glass layer containing a binder, a laser-light-absorbing material, and a glass powder on the glass member along a region to be fused, the glass layer having a melting point and a surface exposed to atmosphere and opposite the glass member;
- and
- irradiating, with a laser light, the glass layer to a temperature greater than the melting point along the region to be fused to gasify the binder and melt the glass powder, thereby fixing the glass layer to the glass member and enhancing laser light absorptance in the glass layer.

4:
- The glass layer fixing method according to claim 3, wherein the binder has a decomposition point, and the melting point of the glass layer is higher than the decomposition point of the binder.
