PURPOSE: A dustproof mask is provided, which makes respiration facilitated in wearing and improves bad smell inhalation. CONSTITUTION: A dustproof mask comprises a fibrous structure material; and nano-fiber web consisting of nano-fibers in which the average diameter is 10~1,500 nanometers. The nano-fiber contains deodorizing agent of 0.1~5.0 weight% against nano-fiber. The nano-fiber web is produced in the electric spinning method. The electric spinning method forms nano-fiber by spraying spinning solution to a collector(4) and laminates the nano-fiber web on the collector.
