Zusammenfassung:	The present invention relates to a non-woven fabric formed from fibers each containing a poly(3-hydroxyalkanoate)-based resin, and provides a non-woven fabric and the like having an excellent property of being hot-melted to other materials. The present invention provides: a non-woven fabric containing fibers, in which the fibers are formed from a resin composition containing a poly(3-hydroxyalkanoate)-based resin, the poly(3-hydroxyalkanoate)-based resin contains a 3-hydroxybutyrate unit, the content ratio of the 3-hydroxybutyrate unit in the poly(3-hydroxyalkanoate)-based resin contained in the non-woven fabric is 91.0 mol% to 97.0 mol% inclusive, and the amount of heat of melting of an endothermic peak in a DSC curve of the non-woven fabric is 50.0 J/g or more; and the like. La présente invention concerne un tissu non tissé formé à partir de fibres contenant chacune une résine à base de poly(3-hydroxyalcanoate) et fournit un tissu non tissé, et similaire, ayant une excellente propriété d'être fondu à chaud vers d'autres matériaux. La présente invention concerne : un tissu non tissé contenant des fibres, dans lequel les fibres sont formées à partir d'une composition de résine contenant une résine à base de poly(3-hydroxyalcanoate), la résine à base de poly(3-hydroxyalcanoate) contient une unité 3-hydroxybutyrate, le rapport de teneur de l'unité 3-hydroxybutyrate dans la résine à base de poly(3-hydroxyalcanoate) contenu dans le tissu non tissé est de 91,0 % en moles à 97,0 % en moles inclus, et la quantité de chaleur de fusion d'un pic endothermique dans une courbe DSC du tissu non tissé est de 50,0 J/g ou plus ; et similaire. 本発明は、ポリ（３－ヒドロキシアルカノエート）系樹脂を含む繊維で形成された不織布に関し、他の材料との熱融着性に優れる、不織布等を提供する。本発明は、繊維を含む不織布であって、前記繊維は、ポリ（３－ヒドロキシアルカノエート）系樹脂を含有する樹脂組成物で形成され、前記ポリ（３－ヒドロキシアルカノエート）系樹脂は、３－ヒドロキシブチレート単位を含み、前記不織布に含まれる前記ポリ（３－ヒドロキシアルカノエート）系樹脂における前記３－ヒドロキシブチレート単位の含有割合が、９１．０モル％以上９７．０モル％以下であり、前記不織布のＤＳＣ曲線における吸熱ピークの融解熱量が５０．０Ｊ／ｇ以上である、不織布等である。
