A conventional electrospinning devices is problematic in that the productivity is low and a droplet, by which a spinning liquid is not formed into fiber but dropped in a drop shape, occurs, to thereby deteriorate the quality of a nonwoven fabric. To solve the above problem, the present invention provides an bottom-up electrospinning devices, comprising: a spinning liquid main tank 1; a metering pump 2; a nozzle block 4; nozzles 5 installed on the nozzle block; a collector 7 for collecting fibers being spun from the nozzle block; and a voltage generator 9 for applying a voltage to the nozzle block 4 and the collector 7, wherein [A] the outlets of nozzles 5 installed on a nozzle block are formed in an upper direction; [B] a collector 7 is located on the top part of the nozzle block; and [C] a spinning liquid discharge device 12 is connected to the uppermost part of the nozzle block 4.
