Abstract: An element array circuit includes one or more first wiring lines, second wiring lines, impedance elements, one or more operational amplifiers, one or more conversion elements, and one or more switchers. The second wiring lines each extend in a direction different from a direction of extension of the first wiring lines. The impedance elements are each coupled to one each of the first and second wiring lines. The operational amplifiers each include a positive input terminal, a negative input terminal couplable to one of the second wiring lines, and an output terminal. The conversion elements are each coupled to the negative input terminal and the output terminal, and each convert a current flowing through the second wiring line coupled to the negative input terminal into a voltage. The switchers are each coupled to one of the conversion elements and come into a conducting state or a nonconducting state.
