Further, a heat insulating material 15 is provided inside the outer wall panel 10. The heat insulating material 15 is made of, for example, a bag of glass fibers and is fixed to the interior material 14 by a fastener such as a tucker.

A corrugated plate 16 made of plastics, cardboard, a metal plate or the like is interposed between the exterior material 13 and the heat insulating material 15 with the wave direction horizontal. This corrugated sheet 1
6, the ventilation layer 17 is formed between the exterior material 13 and the heat insulating material 15 over the upper and lower frame materials 11 and 12. Further, the upper and lower frame members 11, 12 have ventilation holes 18, 19 opened in the ventilation layer 17 between the corrugated plate 16 and the heat insulating material 15, respectively.
Are formed by penetrating vertically.

According to the outer wall panel 10 thus configured, the corrugated plate 16 is interposed between the exterior material 13 and the heat insulating material 15 to prevent the heat insulating material 15 from swelling up, and The ventilation layer 17 can be secured between the heat insulating materials 15. Moreover, since the ventilation holes 18 and 19 opened to the ventilation layer 17 are formed in the upper and lower frame members 11 and 12, moisture in the panel is discharged to the outside through the ventilation holes 18 and 19, and dew condensation occurs in the panel. It can prevent the corrosion of the panel.

In particular, as in the embodiment, the corrugated plate 16 is attached to the exterior material 1
When provided on the third side, the corrugated plate 16 is affected by the outdoor temperature via the exterior material 13 by the heat bridge. For example,
In winter, the corrugated sheet 16 is cooled, and due to the temperature difference between the corrugated sheet 16 and the interior, dew condensation occurs on the surface of the corrugated sheet 16 on the interior material 14 side. Therefore, by forming the ventilation holes 18 and 19 so as to open between the corrugated plate 16 and the heat insulating material 15, moisture between the corrugated plate 16 and the heat insulating material 15 can be discharged to the outside, and the interior material 14 of the corrugated plate can be discharged.
It is possible to prevent dew condensation on the side surface.

Further, the corrugated plate 16 serves as a guide for the wire passage, and can be used also as ventilation holes 18 and 19 for the wire passage. Second Embodiment A second embodiment of the present invention is shown in FIG. The same parts as those in the examples shown in FIGS. 1 and 2 are designated by the same reference numerals, and the description thereof will be omitted.

That is, the outer wall panel 30 of this embodiment.
Is characterized in that the moisture-proof layer 31 is formed on the surface of the corrugated plate 16 made of cardboard or the like on the side of the interior material 14. The moisture-proof layer 31 is made of, for example, a polyethylene sheet or aluminum foil, and is attached over the entire surface of the corrugated plate 16. Also in the outer wall panel 30 thus configured, the same effect as that of the first embodiment can be obtained. Furthermore, by forming the moisture-proof layer 31 on the corrugated plate 16, the moisture-proof property in the panel is further improved.

In each of the above embodiments, the ventilation holes 18, 1
Although 9 is provided at a position where the ventilation layer 17 between the corrugated plate 16 and the heat insulating material 15 is opened, it may be formed at a position where the ventilation layer 17 is opened between the exterior material 13 and the corrugated plate 16. Alternatively, they may be provided at positions on both sides between the corrugated plate 16 and the heat insulating material 15 and between the corrugated plate 16 and the exterior material 13, respectively. Further, although the moisture-proof layer 31 is formed on the surface of the corrugated sheet 16 on the side of the interior material 14, the moisture-proof layer 31 is formed on the surface of the corrugated sheet 16 on the side of the exterior material 13.
May be formed, or the moisture-proof layer 3 may be formed on both sides of the corrugated sheet 16.
1 may be formed. Further, the corrugated plate 16 is not limited to the one made of the circular arc wave as in the above-mentioned embodiment, but is a member capable of preventing the heat insulating material 15 from bulging and ensuring the ventilation layer 17 between the exterior material 13 and the heat insulating material 15. It may be any, for example, a triangular wave or a rectangular wave.
