Abstract
The present invention provides a polyimide solution which does not require a ring-closing process at a high temperature for obtaining a heat-resistant polyimide non-woven fabric and which is hardly affected by atmosphere humidity in fiber production by electrospinning, so that a fiber with a stable diameter can be obtained in any circumstance. A polyimide solution including: (a) a resin containing 50 mol % or more, based on the total amount of the resin, of a structural unit represented by the general formula (1); and (b) a solvent.
