| 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.
