PROBLEM TO BE SOLVED: To provide fibers which use a polylactic acid resin of non-petroleum-based resin under the consideration of environments and improve abrasion resistance and heat resistance that are the weak points of the polylactic acid, and to provide a crimped yarn which has improved crimp percent, abrasion resistance and permanent set resistance. SOLUTION: The synthetic fibers includes a polylactic acid resin (A), a methacrylic resin (B), and a polyamide resin (C). The weight ratio of the polylactic acid resin (A), the methacrylic resin (B), and the polyamide resin (C) in the synthetic fibers satisfies the following relations: ((A)+(B))/(C)=5/95 to 55/45, and (A)/(B)=10/90 to 90/10.
