Radiation detecting element and the radiation image detecting apparatus

Providing suppressing radiation detecting element and the radiation image detecting apparatus artifacts in the image. Radiation detecting element (10) comprises a sensor unit for radiation generates electric charges by being irradiated (103), the charge storage capacitor for storing the generated electric charges (5), the charges accumulated in the charge storage capacitor (5) includes a TFT switch (4) for reading out, a honeycomb shape arrayed plurality of hexagonal pixel (20), are arranged in parallel in a first direction, a switching signal for switching control of the TFT switch (4) a plurality of scan lines (101) but to be output are arranged in parallel in a second direction intersecting the first direction, a plurality of data lines which charge read by the TFT switch (4) is output 3 and comprises a, TFT switch (4), in the first direction, is connected from a different side alternately across data wiring (3) to the data lines (3), and, TFT switch (4 Placement of the source electrode (9) and the drain electrode (13) is arranged to be equal in the first direction.
