In a molded article containing a plant material and a thermoplastic resin, and formed by injection molding, the thermoplastic resin is contained in an amount of 5 to 50% by mass, and the plant material is contained in an amount of 50 to 95% by mass when the total amount of the thermoplastic resin and the plant material is taken as 100% by mass, and a material containing lignin in an amount of 10% by mass or more when the total amount of the plant material is taken as 100% by mass is used as the plant material. And, a process for producing a molded article includes the mixing step of mixing a plant material, water and a thermoplastic resin to obtain a molding material, and the injecting and molding step of injecting the molding material in a molding die and molding the molding material with the molding die to obtain the molded article. In the mixing step, a material containing lignin in an amount of 10% by mass or more when the total amount of the plant material is taken as 100% by mass is used as the plant material, the thermoplastic resin is mixed in an amount of 5 to 50% by mass and the plant material is mixed in an amount of 50 to 95% by mass when the total amount of the thermoplastic resin and the plant material is taken as 100% by mass, water is mixed in an amount of 5 to 200% by mass based on 100% by mass of the plant material, and the plant material, water and the thermoplastic resin are mixed while thermofusing the thermoplastic resin. |
