Radiation detection device

A radiation detection device comprising:

• a radiation detection panel;
• a supporting member having a first surface and a second surface being opposite to the first surface, wherein the radiation detection panel is provided at a side of the first surface;
• an electronic component that is provided on the second surface of the supporting member and drives the radiation detection panel or processes an electric signal output from the radiation detection panel;
• and
• a housing that accommodates the radiation detection panel, the supporting member, and the electronic component,
• wherein a bottom of the housing which faces the second surface comprises a flat portion and a slope portion that is adjacent to the flat portion and becomes closer to the second surface as becoming further away from the flat portion, and
• the electronic component is provided at a position where at least a center of gravity of the electronic component overlaps the slope portion when viewed in a direction perpendicular to the second surface.
