摘要： This invention provides a resin extrusion die capable of suppressing die drool generation and contamination of a resin molded form with generated die drool serving as foreign substances. The resin extrusion die includes a cap through which a molten resin is extruded, and a cover that includes a gas outlet for forming a gap around the tip of a discharge nozzle and covers at least part of the cap so as to form a space between the cap and the gas outlet. The gas outlet forms, around the tip of the discharge nozzle, the gap whose maximum width/minimum width ranges from 1.05 to 2.0, thereby changing a gas supplied into the cover and flowing out of the gap to a turbulent flow.
