The present invention relates to an electrospinning device for manufacturing a nano fiber web. Nozzle pipe bodies provided with multiple pin-shaped nozzles are arranged in the width direction of a base material supplied into a unit of the electrospinning device. Because the amount of supply of a polymer spinning solution that is supplied to each of the nozzle pipe bodies is controlled and the amount of spinning of the polymer spinning solution that is subjected to electrospinning through each of the nozzles is regulated at the same time, nano fiber webs that have different basis weights can be formed to be stacked in the width direction on the same plane of the base material. In addition, the nano fiber webs that have the different basis weights can be formed to be stacked on the same plane of the base material because the respective nozzle pipe bodies and the respective nozzles are controlled individually or simultaneously. Furthermore, variable basis weight stacking formation is allowed in the width direction on the same plane of the base material by, for example, the nano fiber webs that have the different basis weights being formed to be stacked in the nano fiber web in the width direction of the base material. |
