After a glass layer 3 is disposed between a glass member 4 and a thermal conductor 7 along a region to be fused, a laser beam L1 is emitted while the thermal conductor 7 is used as a heat sink, so as to melt the glass layer 3, thereby burning and fixing the glass layer 3 onto the glass member 4. While the glass layer 3 drastically increases its laser absorptance at the time of burning, the thermal conductor 7 serves as the heatsink and draws heat from the glass layer 3, thereby inhibiting the glass layer 3 from falling into an excessive heat input state. Thereafter, another glass member is overlaid on the glass member 4 having the glass layer 3 burned thereonto, such that the glass layer 3 is interposed therebetween. Then, the region to be fused is irradiated therealong with a laser beam, so as to fuse the glass members together.
