PROBLEM TO BE SOLVED: To provide a method and apparatus for producing a laminated polymeric web, which are capable of producing a high quality laminated web. SOLUTION: This method for producing the laminated polymeric web includes arranging a multiple number of nanofiber-forming means 2a, 2b in parallel, for flowing out polymer solution from small holes while impressing a high electric voltage, forming nanofibers 21a, 21b each having different physical properties from these nanofiber-forming means 21a, 21b, stacking/piling the formed nanofibers 21a, 21b on a support sheet 8 one by one, and in the piling process, isolating spaces between the nanofiber-forming means 2a, 2b and support sheet 8 by isolating means 16 obtained by impressing an alternate electric voltage on isolating plates 13 between each of the nanofiber-forming means 2a, 2b so as to be able to pile the nanofibers 21a, 21b one by one uniformly for capable of being laminated, without getting the effect of the high electric voltage impressed on the adjacent nanofiber-forming means 2a, 2b.
