Abstract

See full text

A nanofiber sheet includes: a substrate layer; and a nanofiber layer located on one surface side of the substrate layer and containing nanofibers of a polymer compound. A peripheral edge of the nanofiber layer has a thickness of from 0.1 to 10 μm. The nanofiber layer includes a gradation region having a thickness that gradually increases inward from the peripheral edge. The distance W1 between the peripheral edge of the nanofiber layer and a maximum thickness portion where the thickness becomes the greatest in the gradation region is at least 3 mm. A nanofiber sheet manufacturing method involves depositing nanofibers onto a collecting unit by moving at least either a nozzle or the collecting unit, to thereby manufacture a predetermined nanofiber sheet including a gradation region.
