PROBLEM TO BE SOLVED: To provide a combination weigher capable of maintaining accuracy in combination weighing.SOLUTION: A combination weigher includes weighing hoppers, a control unit and a discharge chute. The weighing hoppers each have a gate for switching between holding and releasing of an article and weigh the article. The control unit calculates a combination of articles to have a predetermined total weight from the articles weighed by the plural weighing hoppers. The discharge chute has a discharge port and discharges the articles released and dropped from the plural weighing hoppers from the discharge port. The plural weighing hoppers include a first weighing hopper group having a distance to the discharge port shorter than a first distance and a second weighing hopper group having a distance to the discharge port equal to or longer than the first distance. The control unit classifies articles composing a combination into plural discharge groups according to the timing of discharging the articles, and preferentially assigns articles held by weighing hoppers of the first weighing hopper group to a prior discharge group to be discharged at earlier timing among the plural discharge groups.
