[Problems to be solved by the invention]

However, in the case of (i), even if the wall material is made permeable, it does not have sufficient moisture permeability, so it has poor moisture absorption and desorption properties, and cannot follow the change in humidity accompanying the temperature change in the room, and dew condensation occurs. In some cases. In the case of (ii), although the moisture absorption is excellent, the moisture release rate is low, so that when the room is in a low humidity, the room is further shifted to a lower humidity side, which may cause an overdry state. In (iii), even though it has an antibacterial function, it does not have a humidity control property, so that when used for a long period of time, mold or the like may be generated due to dew condensation or the like. Furthermore, interior decorative materials having humidity control and antibacterial function have not been developed.
