Spinneret for electrostatic spinning

This spinneret (1) for electrostatic spinning is configured from a structure of an electrically conductive metal material. The structure is provided with a long-axis direction (X), a short-axis direction (Z), and a thickness direction (Y). An inflow port (10) for a spinning starting material fluid is provided to one surface of the structure. A plurality of protrusions (5) are formed on another surface of the structure so as to be aligned along the long-axis direction (X). Each of the plurality of protrusion (5) extends so as to protrude from the structure. The protrusions (5) have, provided to apexes (2) thereof, discharge holes (4) for discharging the starting material fluid. The pitch of the discharge holes (4) exceeds 1 mm. 种静电纺纱用喷丝头(1)，其包含导电性金属材料的结构体，所述结构体具备长轴方向(X)与短轴方向(Z)及厚度方向(Y)，在所述结构体的面具备纺纱用的原料流体的流入口(10)，多个突起(5)以沿着长轴方向(X)排列的方式形成在另面，多个突起(5)的各个以从所述结构体突出的方式延伸，所述突起(5)在其顶部(2)具有喷出原料流体的喷出孔(4)，所述喷出孔(4)的间距超过1mm。
