Cellulose fibers and aluminum are dispersed in a polyethylene resin. The total content of the polyethylene resin and the cellulose fibers is 100 parts by mass, and the ratio of the cellulose fibers is 1 part by mass or more and 70 parts by mass or less, and the water absorption rate. Satisfying the following formula: a cellulose / aluminum-dispersed polyethylene resin composite material, pellets and molded bodies using this composite material, and methods for producing them. [Formula] (Water absorption) <(cellulose effective mass ratio) 2 × 0.01 |
