Problem The present invention provides a PLA and CNC mixture which is improved to have physical properties required for general purposes without increasing environmental issues while keeping biodegradability that is intrinsically necessary for PLA. Solution A PLA and CNC mixture according to the present invention is obtained by adding only CNC which are not chemically modified with a biodegradable substance and has a crystallinity of 90% or more to PLA. Since the CNC dispersed in the PLA serve as crystal nuclei and innumerable crystals are formed, tie molecules extending over a plurality of crystals are formed, thereby forming a PLA crystal network structure, and the structure improves the physical properties of the PLA. Instead of improving PLA by modifying the PLA through crosslinking or polymerization of a substance that has an environmental load or another chemical substance to the PLA, or improving PLA through addition of a chemical substance which has an environmental load, this PLA and CNC mixture improves the physical properties of PLA by modifying the PLA through crystallization and crystal structure change of the PLA itself by adding CNC, which are biodegradable and nontoxic and do not have an environmental load, to the PLA, thereby maintaining the biodegradability of the PLA without degradation.
