PROBLEM TO BE SOLVED: To provide a melt spinning machine for thermoplastic polymer where a plurality of spinnerets are attached to one spinning head so that the yarn extruded in the filament spinning may be evenly and effectively cooled down. SOLUTION: A plurality of spinnerets 3 each of which has a many of spinning holes bored are set to one holder so that the spinnerets may be arranged annularly with a certain interval from one another. Simultaneously, the cooling unit 50 is disposed under the annularly arranged spinneret groups so that it blows out cooling air toward the yarn groups from the outer periphery and/or the inner periphery of the extruded yarn groups out of the group of the spinnerets.
