Abstract
Provided is a nano-fiber manufacturing apparatus which manufactures nano-fibers by an electrostatic explosion, and has a low possibility of explosion even when a flammable solvent is used. The nano-fiber manufacturing apparatus (101) having an ejection unit (110) which ejects solution (200) that is raw material liquid for nano-fibers (200) to a manufacturing space in which the nano-fibers (200) are manufactured by an electrostatic explosion of the solution (200), and a charging unit which charges the solution (200). The nano-fiber manufacturing apparatus (101) includes a gas supply source (103) which supplies safety gas to change an atmosphere of the manufacturing space, in which the solution (200) is ejected, into a low oxygen atmosphere, and a partition (102) which maintains the manufacturing space at a lower oxygen atmosphere than an atmosphere of an outside space of the partition (102).
