Provided are a composite material for producing a natural fiber-containing plastic, said composite material exhibiting an excellent effect of reducing the odor of a natural fiber-containing plastic (in particular, an injection-molded article or a compression-molded article), a method for producing said composite material, a natural fiber-containing plastic having a reduced odor, and a method for producing said plastic. A natural fiber-containing plastic is produced by injection molding or compression molding a composite material that is produced, using a natural fiber and a thermoplastic resin, by a method which involves a step for loading a plant-derived polyphenol to the natural fiber. La présente invention concerne un matériau composite destiné à la production d'un plastique contenant des fibres naturelles, ledit matériau composite présentant un excellent effet de diminution de l'odeur d'un plastique contenant des fibres naturelles (en particulier, un article moulé par injection ou un article moulé par compression), un procédé de production dudit matériau composite, un plastique contenant des fibres naturelles ayant une odeur réduite, et un procédé de production dudit plastique. Un plastique contenant des fibres naturelles est produit par moulage par injection ou par moulage par compression d'un matériau composite qui est produit, en utilisant une fibre naturelle et une résine thermoplastique, par un procédé comprenant une étape destinée à charger un polyphénol dérivé d'une plante sur la fibre naturelle.
