ABSTRACT:
An object of the present invention is to provide a fiber-reinforced resin composition suitable for producing molded articles for products such as electrical and electronic equipment. The object has been achieved by a biodegradable resin composition containing a kenaf fiber, which contains a kenaf fiber in an amount of 10 to 50% by mass. In this case, the biodegradable resin is preferably a crystalline thermoplastic resin, particularly polylactic acid. The average fiber length (number average fiber length of the fibers excluding fragments) of the kenaf fiber is preferably 100 μm to 20 mm, and the kenaf fiber preferably contains a kenaf fiber having a fiber length of 300 μm to 20 mm. As the kenaf fiber, a fiber prepared from bast of kenaf is preferred.
