PROBLEM TO BE SOLVED: To provide a cast-formed article, a scroll, and a casting device facilitating or dispensing with the flattening of a extruded face by a extruding material, and capable of reducing man-hours. SOLUTION: A cope 13 is a mold on the spiral side of a scroll 20, and on the cope 13 a extrusion hole 14 formed into approximately the same shape along the tip of a spiral 20a of the scroll and continuous is provided. In the extrusion hole 14, an extrusion material 15 is made to pass through. The tip of the extrusion material 15 reaches a cavity 6 of a metal mold. The extrusion face 15a of the extrusion material 15 is formed also into approximately the same shape as that of the tip of the spiral 20a. The scroll formed by the casting device of the constitution stated above causes no surface raggedness due to a conventional plurality of extrusion pin traces, and the tip 20a of the spiral of the scroll being the extruded face appears in the shape having a continuous flat part with uniform height by the integrated extrusion material 15.
