The present invention relates to a process for producing a decrystallized cellulose having a reduced cellulose I-type crystallinity from a cellulose-containing raw material in an efficient manner with an excellent productivity. In accordance with the present invention, there is provided a process for producing a decrystallized cellulose from a raw material comprising at least 20% by weight, based on the weight of the raw material excluding water contained therein, of a cellulose having a cellulose I-type crystallinity of more than 33% as calculated from the following formula:Cellulose-type Crystallinity (%)=[()/]&#xd7;100wherein Iis a diffraction intensity of a lattice plane (002 plane) as measured at a diffraction angle 2&#x3b8; of 22.6&#xb0; in X-ray diffraction analysis; and Iis a diffraction intensity of an amorphous moiety as measured at a diffraction angle 2&#x3b8; of 18.5&#xb0; in X-ray diffraction analysis, the process including the step of treating the cellulose-containing raw material using a media-type mill to reduce the cellulose I-type crystallinity of the cellulose to 33% or less, wherein the cellulose-containing raw material has a bulk density of from 100 to 500 kg/m.
