Patent ID: 8884231

Claim:
A radiation detector comprising: a support body; a scintillator layer that is deposited further to the inside than outside edges of the support body and that converts incident radiation into light; a photo detector plate that converts light emitted from the scintillator layer into charge and has a different linear expansion coefficient to that of the support body, the photo detector plate being adhered to the scintillator layer so as to form a gap between the photo detector plate and the support body; and a sealing layer of a resilient body that is poured into the gap and that adheres to a whole of a side face of at least one of: the scintillator layer and a protection layer of the scintillator layer, at least one of the side face of the scintillator and the side face of the protection layer being flat, such that a film thickness at the center portion of the sealing layer is thinner than a film thickness of the sealing layer at the support body side edges and at the photo detector plate side edges.
