The invention provides a combination measuring device allows fast measurement without lowering a measurement accuracy. The combination measuring device respectively accommodates objects (101) in a plurality of containers (102), performs combination calculation by measuring weights of the objects accommodated in the containers, discharges and collects the objects selected for an optimum combination from the containers, and thereby obtaining the weighed objects having a target weight. This combination measuring device includes a plurality of measuring units (1, 2, 3 and 4), and a control portion (50). Each of the measuring units (1, 2, 3 and 4) has a measuring portion (21) for measuring the weight of the object accommodated in the container, and a stock portion (22) for stocking the plurality of containers accommodating the weighed objects. The control portion (50) performs the combination calculation by using weight values of all the objects stocked by the stock portion of each of the measuring units, while selecting at most one container from each of the measuring units, and thereby obtaining the optimum combination.
