Abstract
A method of manufacturing nanofibers according to an aspect of the present invention by electrically stretching a solution in space and depositing the nanofibers in a given region includes: effusing the solution from an effusing body having an effusing hole which allows the solution to effuse in a direction; applying a given voltage between the effusing body and a charging electrode being conductive and disposed at a given distance from the effusing body, using a charging power supply configured to apply the given voltage; and determining a flight path of the solution and the nanofibers such that a length of the flight path of the solution and the nanofibers is longer than a shortest path length which is a length of a shortest imaginary path connecting an end opening of the effusing hole and an accumulation part on which the nanofibers are accumulated.
