Here, there is a slight gap between the substrate 1 and the mask, but since air is blown out from the slit-like hole in the direction of the arrow in FIG. 3, the adhesive beads 4 do not wrap around this gap. In this way, the adhesive beads 4 are selectively distributed on the lower substrate 1 corresponding to the mask openings, and similarly to the first embodiment, the adhesive beads 4 are disposed at the terminal portions and upper and lower substrate cut portions of FIG.
