PURPOSE: To provide a spinning pack hardly causing yarn breakage by eliminating the occurrence of abnormal residence of a polymer in a separation type spinning pack using a metal wire filter.
CONSTITUTION: At least spinneret 11, a pressure-resistant plate 10 and a metal wire filter 8 are laminated to the interior of a separation type pack body 1 and simultaneously, the metal wire filter 8 is constituted so as to laminate a wire net 82 to at least either one face of a sintered metal fiber filter 81 and the outer peripheral edge part 8a of this metal wire filter 8 is held between the pressure-resistant plate 10 and a pack block 6 or the pressure resistant plate 10 and a sealing 7 in which filter material is housed without providing a metal rim in the outer peripheral edge part 8a and the outer peripheral edge part 8a is pressed so that the thickness B of the held part becomes thicker than the thickness A of a part which is not held.
