Abstract
An X-ray flat panel detector includes sensor elements constituted by a plurality of effective pixels that detect X-rays and a plurality of dummy pixels that are arranged adjacent to the effective pixel area and generate electrical signals irrelevant to X-rays, signal lines which read out electrical signals from the respective pixels, scanning lines which scan the respective pixels, a first electrostatic wiring line which distributes static electricity accumulated in the signal lines, and a second electrostatic wiring line which distributes static electricity accumulated in the scanning lines. A plurality of dummy pixels are classified into a DA area where noise superposed on the signal lines are removed and a DB area where noise superposed on the scanning lines are removed. The first and second electrostatic wiring lines are laid out around the sensor elements, and physically disconnected between the DA area and the DB area.
