Abstract: PROBLEM TO BE SOLVED: To provide the manufacturing method and the manufacturing device of a hollow fiber membrane having excellent roundness. SOLUTION: By using the manufacturing device of hollow fiber membrane which is provided with a mouth piece for ejecting a membrane forming raw liquid together with a hollow part forming fluid, a coagulation bath for coagulating the membrane forming raw liquid after ejection, and a touch roller and a first roller for changing a thread passage of a coagulated hollow fiber membrane in order to spin the hollow fiber membrane, the hollow fiber membrane is manufactured. Therein, the length of the hollow fiber membrane between the touch roller and the first roller is made to be 1.01 times to 1.5 times of the length of a tangential connecting the touch roller and the first roller so as to be shortest from a point on each of both circumferences.
