Abstract: A nanofiber sheet has a nanofiber layer composed of an accumulation of nanofibers. The nanofiber sheet has a plurality of membrane-like regions which extend between the nanofibers. The membrane-like regions of the nanofiber sheet each contain a water insoluble polymer and a pigment. The water insoluble polymer contained in the membrane-like regions of the nanofiber sheet is different from a constituent member of the nanofibers. The nanofiber sheet is preferred because it has a plurality of membrane-like aggregate regions, each an aggregate of a plurality of membrane-like regions which are adjacent to each other via a fiber and it has a non-membrane-like region between the membrane-like aggregate regions adjacent to each other.
