PROBLEM TO BE SOLVED: To provide an apparatus capable of producing a fiber having stabilized performances free from dispersion of quality while raising productivity in dry and wet type spinning. SOLUTION: The dry-wet spinning apparatus comprises a coagulating bath 2a, a spinneret 1 in which many spinning hole groups arranged at a fixed air gap G from a liquid level S in which a coagulating liquid L packed in the coagulating bath 2a is formed are bored, a flow pipe 3 installed in a state immersed in the coagulating liquid L and a take-off means 4 of yarn installed below the flow pipe 3. In the dry-wet spinning apparatus, the flow pipe 3 has a funnel-shaped bent pipe part 3a formed in a state spreading toward the upstream side in which the coagulating liquid L flows and a cylindrical straight pipe part 3b provided in the lower part of the bent pipe part 3a and the flow pipe 3 is equipped with a flow rate regulator 5 for feeding the coagulating liquid from all round directions without reducing inside diameter of pipe of the straight pipe part 3b in succession to the straight pipe part 3b and controls flow rate and flow amount of the coagulating liquid which flows down through the flow pipe 3 by a coagulating liquid fed from the flow rate regulator 5.
