Abstract
A 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.
