To provide a novel plasterboard and a method of manufacturing the same.
This novel plasterboard has two first parallel tapered edges on one surface, and has two other parallel tapered ends or tapered edges orthogonal to the first tapered edges on the other surface, or has two first parallel tapered edges on one surface, and has two other parallel horizontal directional tapered ends or tapered edges orthogonal to the first tapered edges in any of the same surface or the other surface, and such the other parallel tapered ends have a width of 100-200 mm. Alternatively, the novel plasterboard has two first parallel tapered edges on one surface, and has two other parallel horizontal directional tapered ends or tapered edged orthogonal to the first tapered edges in any of the same surface or the other surface, and such the other parallel tapered ends have a width such as being 1.5-5 in the ratio of a width of the second parallel tapered edges to a width of the first parallel tapered edges.
