Abstract

A multilayer nanofiber sheet () includes: a nanofiber layer () including nanofibers which comprise a water-soluble polymer compound; a substrate layer () arranged on one surface side of the nanofiber layer (); and a water-insoluble porous layer () arranged on the other surface side of the nanofiber layer (). The three layers are layered, and the multilayer nanofiber sheet is used in a state in which a surface thereof on the porous layer side is arranged so as to face a surface of an object. Preferably, the three layers are layered in a fixed state. Preferably, the porous layer () has a thickness of from 3 to 1000 μm.
