PROBLEM TO BE SOLVED: To provide a combination weighing device preventing falling of articles from weighing hoppers to the exterior of booster hoppers, interference between the gates of the weighing hoppers and the booster hoppers, and the damage of articles due to their falling. SOLUTION: This combination weighing device 1A includes a plurality of heads HA1 to HA9 each comprising a group of hoppers disposed one above the other at a plurality of levels. Articles discharged from the group of hoppers are discharged from an article outlet 10A provided on a lower level than the group of hoppers and substantially in the middle of the arrangement of the heads HA1 to HA9. Among the group of hoppers, a booster hopper 6A disposed on the lowest level has such a shape that sidewalls 20 thereof are sloped in order that a space between the sidewalls 20 gradually narrows from their upper ends toward their lower ends. The space between the sidewalls 20 at the upper ends of the booster hopper 6A is wider than a space between sidewalls of a weighing hopper 5A at their lower ends, with the weighing hopper disposed immediately above the booster hopper.
