ではないかと思われる。As shown in FIG. 5 and FIG. 6, the edge (7) has the edge (7) and the sealing material (3) arranged relative to each other in a state of being covered with only the primary sealant (3A). However, although the moisture impermeability is superior to that of the conventional one, it tends to be slightly inferior to the moisture permeability of the arrangement structure of FIG. After all, the adhesiveness between the secondary sealant (3B) and the metal thin film depends on the primary sealant (3A) and the metal thin film, or the metal thin film removing part (5) and the primary sealant (3A) or the secondary sealant (3
It is better than the adhesiveness with B), and it seems that it has increased moisture impermeability.
