1. A radiation detection module, comprising:
an array substrate including a plurality of photoelectric converters;
a scintillator covering a region in which the plurality of photoelectric converters is located, the scintillator having larger dimensions than the region in which the plurality of photoelectric converters is located when viewed in plan; and
a light-absorbing part located at a side surface and an upper surface of the scintillator, the light-absorbing part being configured to absorb visible light, the light-absorbing part including a material of a surface part of the scintillator that has been discolored by ultraviolet light,
the light-absorbing part being located outward of the region in which the plurality of photoelectric converters is located when viewed in plan.
