Abstract
A nanofiber manufacturing system in which nanofiber is formed from a raw material liquid by electrostatic explosions in a nanofiber forming space and the formed nanofiber is collected and deposited on a main surface of a base sheet. The system includes: a first dielectric belt having dielectric property; sheet conveying devices for conveying the base sheet in the nanofiber forming space; a sheet contacting device for putting a back surface of the base sheet and a first surface of the first dielectric belt into contact with each other; a dielectric belt driving device for running the first dielectric belt in a conveyance direction of the base sheet within the nanofiber forming space while the first surface is kept in contact with the back surface of the base sheet; and a voltage applying device for applying a voltage to the second surface of the first dielectric belt so that dielectric polarization occurs to the first dielectric belt.
