Abstract
In one embodiment, an electrospinning head has a nozzle unit and a control body. The nozzle unit is arranged opposite to a base material, is applied with a voltage, and thereby is capable of discharging a raw material liquid of fiber. The control body is arranged in the vicinity of the nozzle unit so as to extend to an outside of a spinning space between the base material and the nozzle unit. Further, the control body is applied with a voltage of the same polarity as the voltage to be applied to the nozzle unit, and thereby is capable of making an electric field to be generated at the periphery of the nozzle unit.
