PROBLEM TO BE SOLVED: To manufacture a composite material provided with mechanical physical properties such as sufficient strength and others, demonstrating effectively the degradation action as a feature of biodegradable resin, to be degraded in a short time at the time of processing material into a molded product and using the same and manufactured at low cost. SOLUTION: In a composite material composed of paper and resin manufactured by kneading paper with resin, the paper is fibrillated into the fiber shape, and biodegradable resin is provided by containing a water content as a preferable condition for degradation. The average fiber length of fibrillated paper is preferably formed into 2 mm or longer, and the fibrillated fibers are preferably dried into the 1-5% or less water content and kneaded with biodegradable resin. |
