PROBLEM TO BE SOLVED: To provide a gravitational sorter which surely separates and discharges soil and lead bullets. SOLUTION: In the gravitational sorter equipped with a box-shaped main body part 1 where a charging port 2 for soil 11 containing lead bullets is formed at the top of one side wall 1a, a net-shaped member 3 on which the soil 11 is mounted is installed in the main body part so as to vertically partition the main body part, an opening part is formed at the bottom, and a discharge port 9 for the soil 11 transferred from the one side wall 1a along the net-shaped member 3 is formed in the other side wall 1b, a liquid tank 5 installed under the main body part 1 so as to be vertically displaceable and communicating with the inside of the main body part 1 through the opening part, and a drive unit 6 vertically vibrating the liquid tank 5, a partition plate 12 extending in the direction intersecting the transfer direction is installed upright on the upper surface of the net-shaped member 3, and a discharging device 13a discharging lead bullets of which the movement toward the discharge port 9 side is obstructed by the partition plate 12 to the outside of the main body part 1 is arranged on the other side wall 1a side of the partition plate 12.
