PROBLEM TO BE SOLVED: To provide a natural porous mud wall material which is formed of natural materials, free from any environmental problems even when it is disposed, unnecessary for complicated works at site, capable of shortening the construction period and saving the cost, calm in appearance of an earth wall, and capable of conditioning the humidity. SOLUTION: A natural porous earth wall material is formed of a proportioning material consisting of a natural porous material, sepiolite, slaked lime, natural reinforced fiber and water, and cured at normal temperature. The natural porous earth wall material preferably has the composition consisting of 30-50 pts.wt. sepiolite, 60-90 pts.wt. slaked lime, 1-5 pts.wt. natural reinforced fiber, and 20-40 pts.wt. water for 100 pts.wt. natural porous material. In addition, a dry manufacturing method of the natural porous earth wall material comprises a process to mix and stir the natural porous material, sepiolite, slaked lime and natural reinforced fiber, a process to add water to the obtained mixture and mix and stir it, a process to form the obtained proportioned material by a vibration low-pressure molding press, and a process to cure the obtained molding at normal temperature.
