PROBLEM TO BE SOLVED: To provide an electrospinning device capable of high-speed stable electrospinning.SOLUTION: An electrospinning device has at least a set of nozzle block unit 250A, which has first and second nozzle blocks 270, 280 on which nozzles 240 discharging polymer solution are two-dimensionally disposed, and a polymer solution tentative holding part 290 that tentatively holds the polymer solution. The first and second nozzle blocks are disposed in a transportation direction a of a long sheet. The first and second nozzle blocks have multiple pipe bodies 271, 281 with end parts on one side that serve as polymer solution inlets 271a, 281a. Polymer solution outlets 293a, 294a are disposed at the polymer solution tentative holding part 290. The polymer solution inlets 271a, 281a and the polymer solution outlets 293a, 294a are connected by a polymer solution distribution pipe 295.SELECTED DRAWING: Figure 2 【課題】高速でかつ安定した電界紡糸が行える電界紡糸装置を提供する。【解決手段】ポリマー溶液を吐出するノズル２４０が２次元的に配置された第１及び第２ノズルブロック２７０，２８０を有するとともに、ポリマー溶液を一時的に保持するポリマー溶液一時保持部２９０を有する少なくとも１組のノズルブロックユニット２５０Ａを備え、第１及び第２ノズルブロックは、長尺シートの搬送方向ａに沿って配置されており、当該第１及び第２ノズルブロックは、一方の端部がポリマー溶液流入口２７１ａ，２８１ａとなっている管体２７１，２８１を複数本有し、ポリマー溶液一時保持部２９０には、ポリマー溶液流出口２９３ａ，２９４ａが設けられており、各ポリマー溶液流入口２７１ａ，２８１ａとポリマー溶液流出口２９３ａ，２９４ａとの間はポリマー溶液流通パイプ２９５にて接続されている。【選択図】図２
