The present invention relates to a catalyst forming apparatus using a screw extruder. The present invention comprises: a screw extruder which makes the catalysts of a powder state into the catalyst of a dough state and then extrudes them; and a cutter which cuts the catalysts extruded in the screw extruder into a certain length and shape. The cutter comprises a pair of cutting drums which are rotatably arranged, and successively performs cutting while the catalysts pass between the cutting drums. The present invention enables the catalysts extruded in the screw extruder to be formed into the catalysts of a certain shape while directly passing through the cutter, thereby conveniently forming the catalysts into a pellet shape or a sphere shape.
