PROBLEM TO BE SOLVED: To provide a combination metering device capable of improving the operation rate. SOLUTION: In this combination metering device 1, weight detectors 15a-15a, 16a-16a are connected respectively to pool hoppers 15-15 and metering hoppers 16-16. When the combination fails as a result of combination operation, a control unit determines whether the added value of a variable by the prescribed metering hoppers 16-16 and a variable by the pool hoppers 15-15 for supplying a metering object to the metering hoppers 16-16 exceeds a prescribed value set beforehand or not. When determined that the added value does not exceed the prescribed value, the metering object held by the pool hoppers 15-15 is additionally supplied to the metering hoppers 16-16, to thereby avoid over-scale generation in the metering hoppers 16-16.
