Patent ID: 7151263

Claim:
A radiation detector manufacturing method comprising the steps of: fixing a solid state imaging element having a light receiving portion where a plurality of photoelectric conversion elements are arranged and having a first set of electrode pads electrically connected to the photoelectric conversion elements to a support surface of a substrate having external connection electrodes and a second set of electrode pads electrically connected to the external connection electrodes so as to make electrode pads of the first set of electrode pads face corresponding electrode pads of the second set of electrode pads; electrically connecting the corresponding electrode pads in the first and second sets of electrode pads by wiring lines; covering at least the wiring lines and the electrode pads with an electrical insulating covering member; forming a scintillator on the light-receiving portion of the solid state imaging element; tightly sealing the covering member and the scintillator with an electrical insulating organic film; forming a metal thin film which covers a portion of the organic film on the scintillator; and exposing the external connection electrodes.
