ニールむら等が発生し易くなる。[Problems to be Solved by the Invention] However, in the punch tool 8, the r dimension of the base 7' of the sharp-pointed hole 7 at the tip varies by 0.015 to 0.04 mm when the punch tool 8 is manufactured. The size of the bulge 9 generated at the inlet periphery of the stock solution introduction hole 3 shown in FIG. 6, which was punched using the punch tool 8 that caused this variation, varies in size. As a result, when polishing is performed later to remove the protuberance 9, uneven polishing occurs, and the inlet diameter of the stock solution introduction hole 3 becomes uneven. Therefore, when rayon, acrylic, etc. are wet-spun using a spinneret having a stock solution introduction hole 3 with uneven inlet diameter as described above, denier unevenness is likely to occur.
