In fusing a glass layer (3) by irradiation with a laser beam (L1) along a scheduled region (R) for fusion bonding, the glass layer (3) is fused by irradiating the glass layer (3) along the scheduled region (R) for fusion bonding with a laser beam (L1) having a first heat input, and when the fusion ratio of the glass layer (3) in a direction nearly perpendicular to the proceeding direction of the layer beam (L1) exceeds a prescribed level, a change of heat input is made and the glass layer (3) is irradiated along the scheduled region (R) for fusion bonding with a laser beam (L1) having a second heat input lower than the first heat input. Thus, the glass layer (3) is fixed on a glass member (4). Owing to this fusion process, the glass layer (3) is protected from excessive heat input and inhibited from being crystallized in firing. Then, a glass member (5) is fusion-bonded to the glass member (4) via the glass layer (3) which has been little crystallized by virtue of the inhibition. Thus, a fusion-bonded glass structure (1) is obtained. |
