A method of attaching a nanofiber sheet (10) having a nanofiber layer (11) comprising a polymeric nanofiber and a base layer (12) located on one side of the nanofiber layer (11) to a surface of an object. The method includes bringing a side of the nanofiber layer (11) of the nanofiber sheet (10) into contact with the surface of the object under the condition that a surface of the nanofiber layer (11) or the surface of the object is wet. Preferably, the base layer (12) is releasably laminated to the nanofiber layer (11), and the base layer (12) is removed from the nanofiber sheet (10) that is attached to the surface of the object to transfer the nanofiber layer (10) onto the surface of the object.
