A nanofiber laminate sheet including a nanofiber layer containing a cosmetic component or a medicinal component and a water soluble base layer located on at least one side of the nanofiber layer. The water soluble base layer is less water-soluble than the nanofiber layer. The water soluble base layer is preferably constructed of nanofiber portions mingled with filmy portions. The water soluble base layer is preferably a layer of nanofibers in which nanofibers cohere to each other to form the filmy portions at their intersections.
