Radiation detection device

A radiation detection device comprising:

• a radiation detection panel;
• a supporting member having a first surface on which the radiation detection panel is provided;
• a plurality of power supply units that are bonded to a second surface of the supporting member opposite to the first surface of the supporting member;
• a housing that accommodates the radiation detection panel, the supporting member, and the plurality of power supply units;
• and
• a plurality of spacers that are provided on the second surface so as to protrude more than the plurality of power supply units and contact with a bottom of the housing which faces the second surface,
• wherein the plurality of power supply units comprise a first power supply unit and a second power supply unit that are arranged at an interval in a first direction in the second surface,
• the plurality of spacers comprise a pair of first spacers between which the first power supply unit is interposed in a second direction intersecting the first direction in the second surface and which extend in the first direction over both ends of the first power supply unit in the first direction and a pair of second spacers between which the second power supply unit is interposed in the second direction and which extend in the first direction over both ends of the second power supply unit in the first direction, and
• in a case in which the pair of first spacers and the pair of second spacers are viewed from the second direction, at least one of the first spacers and at least one of the second spacers continuously traverse the first power supply unit and the second power supply unit in the first direction.
