Abstract
To realize a small size and high detection accuracy in a substance detection apparatus. A charge detection field effect transistor and a control circuit therefor are provided in each cell, and the control circuit controls the charge detection field effect transistor so that the drain-source voltage and the drain current of the charge detection field effect transistor are always maintained constant. The control circuit may be formed in a CMOS configuration including a small number of elements in a small area using a standard CMOS integrated circuit technique.
