    摘要: Minute masses of a plurality of measuring objects are measured at a time.A multi-lever is prepared, in which a plurality of cantilevers, each having a buried piezoresistance element, is provided. Different measuring object attracting substances are coated on the multi-lever. The multi-lever is driven by a single vibration exciting device. The vibrational frequency is swept within a predetermined range, and the resonance frequency of each cantilever is detected. Frequency changes before putting in and after putting in the measuring object are detected, and based on this, the mass changes are calculated.
