The rotary spinning electrode of elongated shape, serving to carry polymer solution from reservoir of polymer solution or melt into electric field for spinning in devices for production of nanofibers through electrostatic spinning of polymer solutions or melts, including a pair of end faces (2, 3), which are arranged on the carrying mean (1), and between which are mounted the spinning members (41, 42, 43, 44, 45, 46), which are formed of a cord or wire (4). The spinning members (41, 42, 43, 44, 45, 46) are in a skew position to an axis (11) of rotation of the rotary spinning electrode.
