A nanofiber laminate sheet including a nano fiber layer containing a cosmetic component or a medicinal component and a water soluble base layer located on at least one side of the nano fiber layer. The water soluble base layer is less water-soluble than the nanofiber layer. The water soluble base layer is preferably constructed of nano fiber 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.
