PROBLEM TO BE SOLVED: To provide a wet spinneret which has many nozzles formed therein, however does not cause the mutual adhesion of spun single fibers, and can extremely effectively prevent the breakage of the single fibers even in an insufficient coagulation state. SOLUTION: This wet spinneret (1) is used for extruding a spinning solution into a coagulation solution to wet-spin the synthetic fibers, in which island-like isolated nozzle-free portions (A) are disposed at regular distances in a nozzle portion (B) where nozzle groups (2) are formed at approximately same nozzle densities.
