報) 。2. Description of the Related Art Heretofore, inorganic wallboards made of cement compounds have been very widely used. By the way, since these inorganic flat plates have a high specific gravity, there is a problem that a thick wall plate or the like is very heavy and it takes time to carry and construct. Therefore, many wallboards with hollow holes formed in the thickness of the plate product have been proposed for the purpose of reducing the weight, and in order to further increase the strength of this type of hollow product, a reinforcing net is integrated on the front surface or front and back surfaces of the hollow product. There has been proposed a device embedded in the above (for example, JP-A-57-201611 and JP-A-1-99810).

【従来技術の問題点】しかしながら、上記中空壁板は、
中空孔が垂直方向に配列されて固定される場合は問題は

敗すると壁板を見苦しくしてしまう問題があった。However, the above hollow wall plate has the following problems.
There is no problem if the hollow holes are arranged and fixed in the vertical direction, but when fixing them by arranging them in the horizontal direction, condensed water does not flow down and stays inside the hollow holes. There was a problem that caused such. Further, in the case of a wall plate having such a hollow hole, the hollow hole can be used for a wiring duct or the like, but the position where the opening communicating with the hollow hole for taking out the wiring is provided is not clear and the hole is not formed. There was a problem that it made the wallboard unsightly if it failed.
