When melting a glass layer 3 by irradiation with laser light L1 along a region to be fused R, the glass layer 3 is irradiated with the laser light L1 having a first heat input along the region to be fused R, so as to gasify a binder and melt a glass frit 2, and the heat input is switched when the melting ratio of the glass layer 3 in a direction intersecting an advancing direction of the laser light L1 exceeds a predetermined value, so as to irradiate the glass layer 3 with the laser light L1 having a second heat input smaller than the first heat input along the region to be fused R, thereby gasifying the binder and melting the glass fit 2, thus fixing the glass layer 3 to a glass member 4.

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 region to be fused;irradiating the glass layer with first laser light having a first heat input, so as to gasify the binder and melt the glass powder, and, while switching from the first heat input to a second heat input smaller than the first heat input when the melting ratio of the glass layer in a direction intersecting an advancing direction of the first laser light exceeds a predetermined value, irradiating the glass layer with the first laser light having the second heat input along 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; andsuperposing 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 the second laser light along the region to be fused, so as to fuse the first and second glass members to each other. 2. A glass fusing method according to claim 1, wherein the switching from the first heat input to the second heat input is effected by lowering the irradiation power of the first laser light. 3. A glass fusing method according to claim 1, wherein the switching from the first heat input to the second heat input is effected by raising the advancing speed of the first laser light with respect to the glass layer. 4. A glass fusing method according to claim 1, wherein the switching from the first heat input to the second heat input is effected after a lapse of a predetermined time from the beginning of the irradiation with the first laser light. 5. A glass fusing method according to claim 1, wherein the switching from the first heat input to the second heat input is effected when the intensity of thermal radiation light emitted from the glass layer rises to a predetermined value. 6. A glass fusing method according to claim 1, wherein the switching from the first heat input to the second heat input is effected when the intensity of reflected light of the first laser light reflected by the glass layer drops to a predetermined value. 7. A glass 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 region to be fused; andirradiating the glass layer with first laser light having a first heat input, so as to gasify the binder and melt the glass powder, and, while switching from the first heat input to a second heat input smaller than the first heat input when the melting ratio of the glass layer in a direction intersecting an advancing direction of the first laser light exceeds a predetermined value, irradiating the glass layer with the first laser light having the second heat input along 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.
