A fibrous cellulose-containing material which is excellent in dispersibility of cellulose fiber, is easy to dewater, and is not required to contain an organic solvent, and a method for producing the same; and dried fibrous cellulose and a fibrous cellulose composite resin each obtained using the fibrous cellulose-containing material and a method for producing the same. A dispersion liquid of cellulose microfiber is prepared by fibrillating raw material pulp to the extent that the average fiber width is 0.1 μm or more, a fibrous cellulose-containing material is prepared by mixing the dispersion liquid with resin powder having an average particle size of 1 to 1,500 μm, dried fibrous cellulose is prepared by drying the fibrous cellulose-containing material, and the dried fibrous cellulose is kneaded to obtain a fibrous cellulose composite resin.
