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 in a first irradiation 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 in a second irradiation 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, wherein the predetermined region includes the whole of an unstable region where the melting of the glass layer is unstable when irradiated once with the first laser light from the irradiation start position, wherein the unstable region is a region where the glass layer is molten only in a part thereof in the width direction, wherein in the unstable region, the glass layer melts such that the width of a molten region gradually increases from the center part in the advancing direction of the first laser light, wherein in the unstable region, both sides of the molten region in the width direction of the glass layer are unmelted parts of the glass layer, and wherein the binder remaining in the unmelted parts after the first irradiation with the first laser light is removed by the second irradiation, and the laser light absorptance is increased by melting the glass layer, and the laser light absorptance of the molten region of the glass layer is different from that of the unmelted parts of the glass layer.
