2. Description of the Related Art Conventionally, in a structure such as a building, a ceiling plate is arranged at the upper part of the room to hide the structure of the underfloor or the attic and the piping, and to block the indoor ascending airflow and heat the sun. It blocks the light and enhances the lighting effect. Further, in recent years, sound insulation and fire resistance (fire resistance) have been improved in terms of indoor environment and safety.

Conventionally, there have been gypsum boards and asbestos boards as ceiling boards that satisfy such requirements, but the former have the drawbacks that they are weak against water and have insufficient strength.
In addition, the latter not only has poor workability, but also has the serious drawbacks of being easily cracked and impairing human health. Furthermore, both have the disadvantages of high cost, lack of heat insulation, and heavy weight. there were.

Therefore, conventionally, there has been proposed one in which a sound absorbing substance such as a paper honeycomb is filled in the middle portion. However, since the sound absorbing substance has no strength (rigidity), the strength is insufficient as a ceiling plate. There was a problem that it was inconvenient. Further, a multi-layer structure has been proposed in order to improve sound insulation, but there is a problem that the plate thickness becomes thick and the weight and cost increase. Further, since all of them are on-site construction, not only the workability is bad, but also the construction period is long (one week or more).

On the other hand, in order to solve the above-mentioned drawbacks of lacking heat insulation and being heavy, it has been proposed to form an air layer in the middle part. However, the one having an air layer formed in the middle portion has a problem that not only the sound insulation is extremely poor but also the workability is poor.
