A glass layer 3 is irradiated with laser light L2 for temporary firing in order to gasify a binder and melt the glass layer 3, thereby fixing the glass layer 3 to a glass member 4. Here, an irradiation region of the laser light L2 has regions A1, A2 arranged along an extending direction of a region to be fused R and is moved along the region to be fused R such that the region A1 precedes the region A2. The region A2 irradiates the glass layer 3 before the glass layer 3 molten by irradiation with the region A1 solidifies. This makes the glass layer 3 take a longer time to solidify, whereby the binder gasified by irradiation with the region A1 of the laser light L2 is more likely to escape from the glass layer 3. |
