RADIATION DETECTION DEVICE

PROBLEM TO BE SOLVED: To provide an X-ray detection device reducing a thermal effect on an X-ray detection panel from by a circuit board to prevent the generation of image unevenness. SOLUTION: The X-ray detection panel 12 is supported by one surface of a support member 13, the circuit board 14 is supported by the other surface of the support member 13 to accommodate them in a housing 16. A heat conduction part 57 protruding toward the circuit board 14 is provided on an inner surface of the housing 16 facing the circuit board 14. The thermal resistance of a heat conduction path from the circuit board 14 to the housing 16 is reduced by causing the circuit board 14 and the heat conduction part 57 of the housing 16 to be close to each other. Thus, the more heat is conducted to the housing 16. The ratio of the heat thermally conducted to the X-ray detection panel 12 to the heat generated by the circuit board 14 is reduced.
