Radiation detector and method for manufacturing same

Abstract

According to the embodiment, a radiation detector includes an array substrate, a scintillator layer, a wall body, and a filled portion, where the array substrate includes a substrate and multiple photoelectric conversion elements, the multiple photoelectric conversion elements are provided on one surface side of the substrate, the scintillator layer includes a first fluorescent material and is provided on the multiple photoelectric conversion elements, the wall body surrounds the scintillator layer and is provided on the one surface side of the substrate, and the filled portion includes a second fluorescent material and is provided between the scintillator layer and the wall body. The scintillator layer includes a tilted portion in a peripheral edge portion of the scintillator layer; and a thickness of the tilted portion gradually decreases toward the outer side of the scintillator layer. The filled portion is provided on the tilted portion.
