Radiation detection apparatus and radiographic apparatus

A radiation detection apparatus comprising:

• a radiation detection panel configured to detect a radiation;
• a support member that is configured to support the radiation detection panel on one surface thereof and has electrical conductive property;
• a circuit board that is supported on the other surface of the support member and configured to drive the radiation detection panel;
• a flexible circuit board configured to electrically connect the radiation detection panel to the circuit board;
• a heat insulation member arranged between the radiation detection panel and the circuit board;
• a housing that is configured to accommodate the radiation detection panel, the circuit board, the support member, and the heat insulation member and has electrical conductive property;
• a heat conduction member that is accommodated in the housing, connected to the support member and the housing, and configured to achieve electrical conduction between the support member and the housing to conduct heat of the support member to the housing;
• and
• a frame-shaped partition member that is provided between the radiation detection panel and the housing, partitions a space into a first space surrounded by the housing and the support member and a second space surrounded by the radiation detection panel and the entrance window, and suppresses entrance and exit of an atmosphere between the first space and the second space.
