Radiation detection module and radiation image-capturing device

A radiation detection module comprising:

• a radiation detection element including:
• a semiconductor element having a plurality of pixels;
• a plurality of first electrodes arrayed on a first surface of the semiconductor element;
• a second electrode disposed on a second surface of the semiconductor element over the plurality of pixels;
• wherein the radiation detection element outputs detection signals through the first electrode and the second electrode when a radioactive ray comes incident on the pixels;
• a support PCB being placed in parallel with a direction in which the radioactive ray comes incident, and supporting a plurality of the radiation detection elements arranged perpendicularly to the incident direction, and in a direction in which divided pixels corresponding to the first electrodes of the radiation detection element are arrayed;
• and
• a connection section being detachably connected to an external connecting unit, with bias voltage being applied thereto from the connecting unit, outputting the detection signals to the connecting unit, and mechanically holding the support PCB to the connecting unit;
• wherein one of the first electrodes of one of the radiation detection elements is connected to one of the first electrodes of the other radiation detection elements on the support PCB, a position on which the radioactive ray comes incident is identified by simultaneously measuring the detection signals from the first and second electrodes.
