PROBLEM TO BE SOLVED: To provide a flexible multilayer flat yarn improved in slipperiness, antiblocking tendency and split-proofness and excellent in heat resistance and mechanical strength using a polylactic acid-based biodegradable resin. SOLUTION: The multilayer flat yarn is made from two or more of biodegradable resins, wherein the intermediate layer is formed by compounding the polylactic acid-based resin with 0.5-5 wt.% of an inorganic filler, and both of the outer layers are each formed by compounding an aliphatic polyester with 0.5-5 wt.% of an antiblocking agent.
