The objective of this study is to develop a paper-base for the desiccant rotor by using Wakkanai siliceous shale (WSS), which have a high ability of water adsorption / desorption. The paper containing WSS was made by using chemical fibers and WSS fine particles, which was prepared by a ball-milling treatment. In addition, a coating material was prepared by the mixing of WSS fine particles, the resin-emulsion as a binder, a chloride solution for increasing the water adsorption ability. The water adsorption amount of the paper containing WSS showed two times higher than that of the original paper, at the over 70%RH of high humidity range, because of capillary condensation by the meso-pore in the WSS. The water adsorption amount of paper containing WSS evaluated from the cyclic test gave 22 g/m2 by the impregnation of chloride solutions. The initial water adsorption speed also increased by using coating material. It was recognized that the application of the coating material to the paper surface accompanied with the impregnation of chloride solutions improved the water adsorption speed and amount.
