(57) [Summary] [PROBLEMS] The problem to be solved by the present invention is to have biodegradability, excellent flexibility, mechanical strength, heat resistance, moldability, dimensional stability, and storage stability. Another object of the present invention is to provide a nonwoven fabric made of lactic acid-based copolyester. A lactic acid component (A), a dicarboxylic acid component (B), and a diol component (C) are contained as structural units. A nonwoven fabric composed of a lactic acid-based copolyester having a melting point of 110 ° C. to 190 ° C., and a lactic acid component (A), a dicarboxylic acid component (B), a diol component (C), and a high molecular weight agent (D) as structural units. A nonwoven fabric made of lactic acid-based copolyester having a melting point of 110 ° C to 190 ° C. |
