PROBLEM TO BE SOLVED: To provide a screw feeder capable of stably discharging powder and grain and a screw with a blade. SOLUTION: In this screw feeder 10, a screw shaft 4 with a terminal end 3 is fitted into a cylinder-like trough 2 having one end to which the powder and grain m is introduced and the other end at which a discharge port 1 is formed in such an attitude that the terminal end 3 faces the discharge port 1, and the screw shaft 4 is rotated to carry the powder and grain m from one end of the trough 2 to the discharge port 1. The carrying direction of the powder and grain m is aligned with the thrust direction of the screw shaft 4. Further, the powder and grain m carried to the discharge port 1 is discharged to the outside of the trough 2 through the discharge port 1 while being agitated properly by the blade 5.
