Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a composite spinneret capable of reducing a flow channel pressure loss generated at the composite spinneret and dealing with a large flow of polymer in manufacturing a composite fiber.SOLUTION: A composite spinneret discharges a composite polymer consisting of a first component polymer and a second component polymer. A flow channel of the first component polymer and a flow channel of the second component polymer curve at a section between adjacent branch points in each flow channel and are integrated in a lower stream.SELECTED DRAWING: Figure 1 【課題】複合繊維を製造するにおいて、複合口金にて生じる流路圧損を小さくし、大流量のポリマーにも対応できる複合口金を提供すること。【解決手段】第１成分ポリマー、第２成分ポリマーによって構成される複合ポリマー流を吐出するための複合口金は、前記第１成分ポリマーの流路、前記第２成分ポリマーの流路は、各流路で隣り合う分岐点と分岐点の間で湾曲して形成されており、それぞれの流路が下流で一体となっている。【選択図】図１
