PURPOSE:To obtain a molded article such as a steering wheel of automobile, having improved wear resistance, proper degrees of hygroscopicity and frictional resistance, obtained by blending a resin material with a specifically pretreated cellulosic aggregate, injection molding the blend. CONSTITUTION:A cellulosic material (e.g., crushed chip, pulp, etc.) is dried to <=15wt% water content, a urea resin solution is added to the processed material, which is dried at 100 deg.C-250 deg.C, crushed to prepare neutralized finely divided hardened aggregate having 100-150 meshes particle diameter, <=5wt% water content, and 6-7pH. A resin material is blended with 20-60wt% of the neutralized finely divided aggregate and injection molded.
