A multi-stage vacuum kneading-extruder includes a degassing chamber for storing material to be processed and reducing pressure of space for storing the material, a kneading-conveyer device for kneading while conveying the material sent from the degassing chamber, and an extruding mechanism for extruding the kneaded material, at a conveyer terminal end of the kneading-conveyer device, into a predetermined shape. The kneading-conveyer includes a pair of conveyer screws disposed one after another in a conveying direction of the material and a grinding-kneading mechanism interposed between the front and rear screws. The grinding-kneading mechanism includes a plurality of unit kneading mechanisms disposed in opposition to each other relative to the material conveying direction. Each of the unit kneading mechanisms includes an un-rotatable stationary disc, a rotary disc rotatable relative to the stationary disc and a stationary filter interposed between the stationary and rotary discs.
