A radiological imaging device (20A-20E) has a panel section (30) which houses radiation conversion panels (92, 600) for converting radiation (16) to a radiological image, and a control section (32) which is disposed on the panel section (30) and which controls the radiation conversion panels (92, 600). The control section (32) is thicker than the panel section (30), or protrudes from the panel section (30).
