The present invention relates to an injection nozzle for electrospinning including a nozzle body and an air jacket member detachably coupled with each other, and needle members coupled to the bottom surface of the nozzle body via injection holes of the air jacket member. The electrospinning device basically performs air electrospinning for injecting a fiber solution together with air while discharging the fiber solution through the needle members, and the needle members are exposed at the ends thereof by a length long enough to carry out error-free pure electrospinning without air injection if the air jacket member is separated. Therefore, pure electrospinning or air electrospinning can be selectively carried out.
