1. A radiation detection apparatus comprising:
a direct-detection-type radiation detector provided in plurality and configured to be arranged in a planar manner; and
a semiconductor integrated circuit configured to perform a control operation of the radiation detector or processing on a signal from the radiation detector,
wherein the radiation detector and the semiconductor integrated circuit are connected via a mounting substrate,
wherein the mounting substrate is connected to the plurality of the radiation detectors and is disposed so as to be superimposed within areas of the plurality of the radiation detectors in a plan view viewed from a side of a light-receiving surface of the plurality of the radiation detectors, and
wherein the semiconductor integrated circuit is disposed on a back side of the light-receiving surface so as to be included within a partial area of one of the plurality of the radiation detectors and a partial area of the mounting substrate in the plan view.
