Beschreibung
Zusammenfassung:	Provided is a laminate characterized by having at least one polylactic acid resin-containing layer (C) with a thickness of 10-500 nm on at least one surface of a fibrous structure (B) containing a water-soluble resin (A). Also provided is a production method for the laminate, said method being characterized in that water or an aqueous solution is applied to the joining surface of the fibrous structure (B) and the polylactic acid resin-containing layer (C). A laminate according to the present invention exhibits superior tracking, adhesion and coating properties relative to flexible, curved objects, exhibits superior compatibility to organs such as skin and internal organs, and, because the fibrous structure (B) containing a water-soluble resin (A) can easily be removed from the polylactic acid resin-containing layer (C) by means of the aqueous solution, is optimal for use in materials for external use on the skin, such as wound-covering materials, adhesion-preventing materials, and skin care products.
