A glass layer (3) is fixed on a glass member (4) by fusing the glass layer (3) by irradiation with a laser beam (L1) along a scheduled region (R) for fusion bonding, with the irradiation power of the laser beam (L1) being so controlled as to keep the glass layer (3) at a temperature which is higher than the melting point (Tm) and lower than the crystallization temperature (Tc).  In fixing the glass layer (3), the laser beam absorptivity of the glass layer (3) is rapidly enhanced by the fusion of the glass layer (3).  But, the irradiation power of the laser beam (L1) is so controlled as to keep the glass layer (3) at a temperature which is higher than the melting point (Tm) and lower than the crystallization temperature (Tc), whereby the glass layer (3) is protected from excessive heat input and thus inhibited from being crystallized in firing.  Then, a glass member (5) is fusion-bonded to the glass member (4) via the glass layer (3) thus reduced in crystallization.  Thus, a fusion-bonded glass structure (1) i
