Cellulose powder pellets and a method for manufacturing the same, wherein dried cellulose powder produced by pulverizing paper or wood is impregnated with a liquid fireproof agent, and then the cellulose powder is dried to produce the heat-resistant cellulose powder. The heat-resistant cellulose powder, lubricant and pulverized polyethylene terephthalate resin are put into the heating kneader, and the mixture is kneaded under compression and heating to produce a paste material. The paste material is supplied to a twin screw extruder, the stick like parison having a small diameter extruded from the end of the extruder is cut into pieces, and the pieces are air-cooled to produce the cellulose powder pllets.
