A combination weigher of the present invention is configured such that a plurality of weighing hoppers ( 4 ) are divided into base groups (FG 1 , FG 2 ) and adjustment groups (CG 1 , CG 2 ) between them, collecting funnels ( 7 A, 7 B) are provided at a lower part of a collecting chute ( 6 ), and movable plates ( 10 ) are provided to selectively discharge the objects to weighed from each adjustment group (CG 1 , CG 2 ) to one of the collecting funnels ( 7 A, 7 B). A control unit ( 20 ) is configured to combine each adjustment group with either one of the base groups to create discharge groups each including one base group and made up of the weighing hoppers ( 4 ) arranged continuously and to perform combination calculation to determine weighing hoppers ( 4 ) forming an optimal combination in each discharge group, and configured to cause the movable plate ( 10 ) to move according to the discharge group to which each discharge group belongs and to cause the weighing hoppers ( 4 ) forming the optimal combination to discharge the objects to be weighed.
