1. A glass fusing method for manufacturing a glass fusing structure by fusing first and second glass members together, the method comprising the steps of:

  • disposing a glass layer on the first glass member along a region to be fused, the glass layer being formed by removing an organic solvent and a binder from a paste layer containing a glass powder, a laser-absorbing material, the organic solvent and the binder;

    irradiating a part of the glass layer with a first laser beam, so as to melt the part of the glass layer and form a laser-absorbing part in the glass layer;

    irradiating the region to be fused therealong with a second laser beam while using the laser-absorbing part as an irradiation initiation position, so as to melt the glass layer and fix the glass layer to the first glass member; and

    overlaying the second glass member on the first glass member having the glass layer fixed thereto such that the glass layer is interposed therebetween, and irradiating the region to be fused therealong with a third laser beam, so as to fuse the first and second glass members together.
