A combination weigher capable of performing a high-speed operation regardless of a characteristic of a weighed object comprises plural weighing units and a lower collecting chute and a lower collecting hopper which collect the objects which have been discharged from upper collecting hoppers of weighing units and discharge them, and a control unit. The control unit repetitively performs a process for determining a discharge combination from weighing hoppers in all weighing units, a process for causing weighing hoppers making up the discharge combination to discharge the objects, a process for causing all of the upper collecting hoppers to discharge the objects; and a process for causing the lower collecting hopper to discharge the objects.
