To provide an inorganic multi-layer plate which can sufficiently exert the moisture conditioning property and the gas adsorptiveness of carbide derived from plants, and has large strength.

The inorganic multi-layer plate 4 is formed of front and rear surface layers 1 which contain mineral fibers, inorganic fine particles, and a binder as main ingredients, and an intermediate layer 2 interposed therebetween, which contains carbide 3 derived from plants, open-type inorganic foam, and a binder as main ingredients. The front and rear layers 1 each have water vapor permeative property, and therefore the moisture conditioning property and the gas adsorptiveness of carbide 3 derived from plants contained in the intermediate layer 2 is sufficiently exerted. Further, by virtue of the front and rear layers 1, the strength of the multi-layer plate 4 is enhanced, and therefore the multi-layer plate is excellent as an interior finish board.
