Zusammenfassung:	PROBLEM TO BE SOLVED: To realize a weight measuring apparatus by which the weight of an object to be measured can be measured with good accuracy by using a weight sensor having a comparatively small dynamic range by making the weight of objects other than the object to be measured born by an elastic body so as to be offset. SOLUTION: The weight measuring apparatus is constituted of an elastic body 3 and an outer-circumferential support member 4 which support an object to be measured. In addition, it is constituted of a weight sensor 5 which measures a value in which the weight of the object to be measured, supported by the elastic body is subtracted from the weight of the object to be measured. In addition, an A/D conversion means 6 which A/D-converts the signal of the weight sensor 5. In addition, it is constituted of a computing means 7 which processes the signal of the A/D conversion means 6. Consequently, the weight of objects other than the object to be measured is born by the elastic body 3 so as to be offset. Thereby, the weight of the object to be measured can be measured with good accuracy by using the weight sensor 5 whose dynamic range is comparatively small.
