Patent ID: 7705317

Claim:
A radiation imaging device comprising: a rectangular-shaped planar scintillator film which emits light with a predetermined wavelength in response to an incident of X-ray; an image sensor which includes: a rectangular-shaped silicon substrate having an X-ray incident surface, a photodetecting section arranged opposite side to the X-ray incident surface for detecting the light with a predetermined wavelength emitted by the scintillator film, and an electrode section arranged on a same side as the photodetecting section of the silicon substrate, where the photodetecting section is in contact with one of the surfaces of the scintillator film, and the electrode section is exposed to the outside of the scintillator film; and a circuit board having a circuit part and an electrode section both are mounted on one of surfaces of a substrate, the other of the surfaces of the substrate of the circuit board covering whole area of the scintillator film, the circuit board being disposed on the other surface of the scintillator film the electrode section of the circuit board being electrically connected to the electrode section of the image sensor by a wire, the electrode section of the image sensor and the electrode section of the circuit board being laterally aligned in a planar view, and the electrode section of the image sensor being exposed to outside of the circuit board.
