Zusammenfassung:	To provide a spun-bonded nonwoven fabric having a high biomass degree, and containing a resin having a sufficiently high biodegradable speed.SOLUTION: A spun-bonded nonwoven fabric is constituted by combining webs composed of a continuous fiber containing a molten matter of a plant-originated polybutylene succinate resin into a sheet state. The spun-bonded nonwoven fabric is constituted by combining webs which is composed of a continuous fiber containing a molten matter of a plant-originated polybutylene succinate resin, and which has a basis weight measured according to JIS L1913(in 2010) of 15 g/m2 or more and 105 g/m2 or less, and a permeability of 750 cc/cm2 sec to 2620 cc/cm2 sec into a sheet state.SELECTED DRAWING: None 【課題】高いバイオマス度であり、かつ生分解性速度が十分速い樹脂を含むスパンボンド不織布を提供すること。【解決手段】植物由来ポリブチレンサクシネート樹脂の溶融物を含む長繊維からなるウェブをシート状に結合してなるスパンボンド不織布。ＪＩＳＬ１９１３（２０１０年）に従い測定される目付が１５ｇ／ｍ２以上１０５ｇ／ｍ２以下であり、通気度が７５０（ｃｃ／（ｃｍ２・秒））乃至２６２０（ｃｃ／（ｃｍ２・秒））である、マルチシート用の植物由来ポリブチレンサクシネート樹脂の溶融物を含む長繊維からなるウェブをシート状に結合してなるスパンボンド不織布。【選択図】なし
