PROBLEM TO BE SOLVED: To provide a spinneret for sea-island type conjugated fibers in which the high-quality sea-island type conjugated fibers can efficiently be formed.;SOLUTION: The spinneret 1 for forming the sea-island type conjugated fibers from a sea component and an island component is provided. The spinneret includes: a sea component flow body 13 having a plurality of sea component flow holes 32 formed so as to extend in the vertical direction; a sea component introduction part 30 for introducing the sea component into the sea component flow holes 32; a plurality of island component flow pipes 33 inserted into the plurality of sea component flow holes 32, respectively, and extending along the vertical direction; island component introduction parts 31 for introducing the island component into the island component flow pipes 33; and conjugated fiber collecting parts 40 for collecting the conjugated fibers under the sea component flow holes 32 and island component flow pipes 33. The plurality of sea component flow holes 32 are formed so as to be distributed in any on circumferences of a plurality of concentric circles, and composed of the outermost sea component flow holes 321 disposed on the outermost circle on the farthest outside in the dimensional direction in the concentric circles and the inside sea component flow holes 322 disposed on the circles on the inside of the outermost circle. In the spinneret 1, the cross-sectional area of the outermost sea component flow holes 321 is larger than that of the inside sea component flow holes 322.;COPYRIGHT: (C)2010,JPO&INPIT
