To provide a method for producing an extrusion-molded resin article by which, upon the production of an extrusion-molded article or the like including an annular olefin resin which is necessary to be performed at low temperature, the sticking and deposition of the mucus of a resin to the vicinity of a die outlet are suppressed.
Resin mucus stuck to the vicinity of the die outlet is produced since a resin raw material oxidized and deteriorated before melt kneading or the like disturbs the flow of a melted resin from the die. Then, by subjecting the resin raw material to deoxidation treatment beforehand, the oxidation and deterioration of the resin raw material is suppressed, and the sticking and deposition of resin mucus in the vicinity of the outlet of the die are suppressed.
