A multilayer nanofiber sheet ( 10 ) includes: a nanofiber layer ( 11 ) including nanofibers which comprise a water-soluble polymer compound; a substrate layer ( 12 ) arranged on one surface side of the nanofiber layer ( 11 ); and a water-insoluble porous layer ( 13 ) arranged on the other surface side of the nanofiber layer ( 11 ). 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 ( 13 ) has a thickness of from 3 to 1000 μm. |
