<P>PROBLEM TO BE SOLVED: To provide a nanofiber production apparatus capable of stably mass-producing nanofiber with desired performance. <P>SOLUTION: An electrospinning device 20 comprises: a conductive housing 100; a collector 150 attached to the housing 100 through an insulating member 152; a nozzle block 110 opposing the collector 150 and including a plurality of nozzles 112; a power unit 160 applying a high voltage between the nozzle block 110 and the collector; an auxiliary belt disposed in a position surrounding the collector; and an auxiliary belt driving device 174 rotating the auxiliary belt in accordance with a conveyance speed for a long sheet. In the power unit 160, one of positive and negative electrodes is connected to the collector 150, and the other electrode is connected to the nozzle block 110 and the housing 100. The insulating member 152 has an outer edge disposed outside an outer edge of the collector and has a thickness "a" satisfying a relationship of a≥6 mm, and a distance "b" between the outer edge of the insulating member 152 and the outer edge of the collector 150 satisfies a relationship of a+b≥50 mm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
