PROBLEM TO BE SOLVED: To provide a spinneret capable of readily and surely securing a nozzle tip into a mounting hole in a spinneret body without causing breakage, etc., while ensuring the complete sealability between the mounting hole of the spinneret body and the nozzle tip and producible at a low cost and a method for producing the spinneret. SOLUTION: This spinneret is obtained by composing a spinneret body 12 of at least two mutually screwed up platy members and installing a first shoulder part engaging with the first platy member and a second shoulder part engaging with the second platy member in a nozzle tip 14 and interposing a deformable annular sealing material in at least either one of a space between the first platy member and the first shoulder member and a space between the second platy member and the second shoulder part in the spinneret comprising the spinneret body 12 and the nozzle tip 14 secured into the mounting hole 13 bored in the spinneret body 12 and separate from the spinneret body 12 forming spinning holes.
