Abstract:
1. An energy ray detecting element, comprising: a semiconductor substrate having an energy ray sensitive region that generates charges in response to the incidence of energy rays; an output section accumulating the charges generated in said energy ray sensitive region, and outputting a current signal or a voltage signal corresponding to the accumulated charge amount; a plurality of electrodes, each positioned so as to cover a part of said energy ray sensitive region and transferring the charges generated in said energy ray sensitive region to said output section; and a voltage dividing circuit having terminals directly and electrically connected to said electrodes and coincidentally providing predetermined potentials to said electrodes through said terminals so as to form a single potential well with respect to said energy ray region, said voltage dividing circuit including a plurality of voltage dividing resistors serially connected to each other, each of said voltage dividing resistors providing a corresponding DC output potential to the associated one of said electrodes by dividing a DC output voltage from a DC power supply.
