<P>PROBLEM TO BE SOLVED: To provide a radiation detector in which microphonic noise can be conveniently suppressed. <P>SOLUTION: A flat-panel detector 10 has a structure in which an X-ray detector main unit 11 is accommodated in a housing 12 in a sealed state. The X-ray detector main unit 11 comprises a scintillator layer 13 and an active matrix substrate 14. The scintillator layer 13 includes a reflective layer 15 formed on the upper surface thereof. The active matrix substrate 14 includes a required number of pixels 16 arranged two-dimensionally on the front surface side thereof, and the active matrix substrate 14 also includes a first conductive layer 17 formed on the back surface side thereof. The active matrix substrate 14 is supported on a base 18 of the housing 12 via the first conductive layer 17. The X-ray detector main unit 11 is therefore accommodated between the base 18 and a protective cover body 19, and the protective cover body 19 is bonded at edge parts of the base 18 through adhesive layers 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
