Abstract: A honeycomb-shaped ceramic structure having dehumidifying capacity formed by extruding into a honeycomb shape a composition containing zeolite powder having moisture adsorbing property, inorganic fiber, and inorganic binder and by baking the composition in the honeycomb shape. The product displays an excellent dehumidifying capacity at a relatively high temperature of 50.degree.-100.degree. C. The honeycomb-shaped ceramic structure is produced by extruding the composition containing zeolite powder, inorganic fiber and inorganic binder into a honeycomb shape and by baking it at 400.degree.-700.degree. C. after drying.
