A combination weighing apparatus includes a plurality of hoppers each having a gate and being capable of accommodating an article and discharging the article therefrom upon opening of the respective gate, a drive device for selectively opening and closing the gate and maintaining the gate in an opened position when in a conducting state, and a control device for controlling the drive device and having a weighing mode, in which the gates of the hoppers selected for combination are opened to combine the respective articles, and a discharge mode in which the articles within the hoppers are discharged while the gates are maintained in the opened position. The control device performs a control of closing the gate when during the discharge mode the opening of the gate lasts a predetermined length of time. The control device also performs a control of setting a closing duration of the gate during the discharge mode to a value longer than a closing duration of the gate during the weighing mode.
