Abstract

A radiation imaging apparatus includes an attenuation member on the back surface side opposite the radiation incident surface of a radiation detection unit. The attenuation member is configured to reduce unexpected appearance of a part disposed on the back surface side of the radiation imaging apparatus, the unexpected appearance of which occurs due to backscattered radiation reflected by the structured part on the back surface side of the radiation imaging apparatus. The attenuation member includes a material having a radiation transmittance higher than that of the part and covers the end portion of the outline of the part that overlaps the radiation detection unit in orthogonal projection onto the surface opposite the incident surface of the radiation detection unit, and the area of the attenuation member is smaller than that of the radiation detection unit.
