A winding device includes a nozzle holding mechanism for holding a plurality of nozzles in substantially parallel with each other, a nozzle rotation driving mechanism for rotating the nozzle holding mechanism about a rotation axis being substantially parallel with the plurality of nozzles, a spool supporting mechanism for supporting a plurality of spools in substantially parallel with each other, a spool rotation driving mechanism for rotating the spool supporting mechanism about a rotation axis being substantially parallel with the plurality of spools and being coaxially with or substantially parallel with the rotation axis of the nozzle holding mechanism, and a control unit for controlling the spool rotation driving mechanism in such a manner as to rotate the spool supporting mechanism in synchronism with rotation of the nozzle holding mechanism.
