<p>A device and method for manufacturing by electrospinning a nonwoven fabric comprising glass filaments having ultrafine diameters (e.g., having diameters 0.3-5µm), and in particular, for manufacturing an ultrathin glass nonwoven fabric (e.g., having a 50µm-1mm thickness) for forming high frequency circuit substrates with a low dielectric constant and low loss, and a glass nonwoven fabric are provided. This glass nonwoven fabric manufacturing device is provided with a glass material supply means for supplying a rectangular glass material, a conveyance means for conveying at a prescribed velocity said supplied rectangular glass material, a guide electrode means which feeds said conveyed rectangular glass material, is formed from a conductive material and is an electrode, a heating means for melting and softening said fed rectangular glass material, a target member which comprises a conductive material arranged at a prescribed interval opposite of said guide electrode means, and a DC power supply means for applying a DC voltage between the guide electrode means and the target member.</p> |
