<P>PROBLEM TO BE SOLVED: To provide a combinational weighing apparatus for improving the rate of operation while avoiding reduction of weighing accuracy. Ž<P>SOLUTION: This combinational weighing apparatus 1 comprises a controller 30 for controlling the delivery of an article from each weighing hopper W based on the weighing result by a plurality of load cells R. Regarding the weight value of the article, a target value, a first upper limit value larger than the target value, and a second upper limit value larger than the target value and smaller than the first upper limit value are set. When a first condition is established where a combination of the weighing hoppers W for achieving the weight value that is the target value or larger and the first upper limit value or smaller exists and the total number of weighing hoppers W reserving articles is a predetermined value or larger, the controller 30 delivers the article from the weighing hopper W related to the combination. When the first condition is not established, and when a second condition is established where a combination of the weighing hoppers W for achieving the weight value that is the target value or larger and the second upper limit value or smaller exists regardless of the total number of weighing hoppers W reserving the articles, the controller 30 delivers the article from the weighing hopper W related to the combination.
