PROBLEM TO BE SOLVED: To provide a melt-spinning device solving abnormal staying of a polymer in a spinneret pack and not generating yarn group cooling unevenness of spun yarns in aiming at the multiple spinning by using a divided spinneret. SOLUTION: This melt spinning device is to melt spin thermoplastic multi-filament yarn groups consisting of multiple spindles from a single spinneret pack 1 at the same time is constituted by dividing ejection hole groups corresponding to each of spindles, further forming each divided spinnerets bored with each divided ejection hole groups on multiple concentric circles and seal members for separating each of the polymers separately supplied for each of the separated ejection hole groups and including separated flow passage groups formed as separated by the groups corresponding to each of the filtering mediums and filter layer groups for supplying the polymers independently for each of the divided flow passage groups formed and divided by the groups corresponding to one to one each of the spindles.
