Provided is a biodegradable nonwoven fabric that is biodegradable and is extremely excellent in elasticity.　This biodegradable nonwoven fabric is configured from fibers including a biodegradable thermoplastic resin, and is characterized in that a SS curve obtained by stretching in a 30°C environment does not have a yield point in the displacement 0-40 mm interval. L'invention concerne un tissu non tissé biodégradable qui est biodégradable et est extrêmement excellent en termes d'élasticité.　Ce tissu non tissé biodégradable est conçu à partir de fibres comprenant une résine thermoplastique biodégradable, et est caractérisé en ce qu'une courbe SS obtenue par étirement dans un environnement à 30°C n'a pas de limite apparente d'élasticité dans l'intervalle de déplacement de 0 à 40 mm. 生分解性を有するとともに、極めて優れた伸縮性を有する生分解性不織布の提供。　生分解性熱可塑性樹脂を含む繊維から構成された生分解性不織布であって、３０℃雰囲気下で伸長して得られるＳＳカーブが変位０ｍｍ～４０ｍｍ区間に降伏点を有しないことを特徴とする、生分解性不織布。
