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

  • disposing a glass layer on the first glass member along a ring-shaped 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 the region to be fused therealong from an irradiation initiation position in the region to be fused to the irradiation initiation position with a first laser beam and successively irradiating a predetermined region extending from the irradiation initiation position in the region to be fused therealong with the first laser beam again, 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 second laser beam, so as to fuse the first and second glass members together.
