PROBLEM TO BE SOLVED: To provide a nanofiber laminate having uniform and small fine pore diameter owing to a three-dimensional structure of the nanofiber laminate, produced by an electrospinning process using a polyurethane resin, and eliminating the problems of an organic solvent by changing the solvent of a spinning solution from the organic solvent to an aqueous solvent. SOLUTION: There is provided the nanofiber laminate obtained by the electrospinning process, wherein the nanofibers are formed by electrospinning of a polyurethane resin emulsion containing a water-soluble polymer.
