To provide a spinneret pack for melt-spinning a conjugated fiber capable of applying a bolt tightening force to a spinneret so as to suppress the generation of polymer leakage when the spinneret pack has a structure to seal the polymer leakage by jointing a plurality of spinneret boards constituting the spinneret with each other by metal touch.

The spinneret pack is at least provided with: a spinneret, for spinning the conjugated fiber by receiving multiple molten polymers inside to form a conjugated polymer flow, having a plurality of spinneret boards laminated on top of one another and joined together by metal touch; a pack body for mounting the spinneret; a cap holder for attaching the spinneret to the pack body while keeping a prescribed gap therebetween; and a tightening bolt for tightening the cap holder, which holds the spinneret, to the pack body, and for applying a sealing force to the metal seal part of the spinneret board. A spacer for reducing the deformation of the gap when tightening the cap holder to the pack body with the tightening bolt is placed at least at "a position between the cap holder and the pack body" where the deformation increases, and is made to be adjustable to decrease the variation of the deformation distribution of the gap.
