PROBLEM TO BE SOLVED: To provide a new sorter of waste resin materials which separates recyclable plastic materials and non-recyclable unnecessary materials from each other by a relatively simple means. SOLUTION: In the sorter of waste resin materials, a plurality of feed mechanisms 2 each constituted by arranging a pair of rotating screw shafts 1, 1 so as to leave a small space between them are disposed in parallel, the feed mechanisms 2 are inclined so that the feed side of the waste resin materials is located at an upper position, and the upper parts of the screw shafts 1, 1 have a surface having a small frictional resistance and the lower part of the screw shafts 1, 1 have a surface having a large frictional resistance.
