Radiological imaging apparatus, manufacturing method of the same, and imaging system

A manufacturing method of a radiological imaging apparatus, the method comprising:

• a process of preparing each of a first panel where a plurality of radiation detecting elements are arrayed on a first substrate, and a second panel where a plurality of radiation detecting elements are arrayed on a second substrate;
• and
• a process of adhering a second-panel side face of the first panel and a first-panel side face of the second panel to each other by a sheet-shaped adhesion part which has radiation absorbency, so that the first panel and the second panel are overlaid on each other in planar view as to an upper face of the first substrate,
• wherein the adhesion part is configured so that change in relative positions of the first panel and the second panel in a planar direction parallel to the upper face of the first substrate is smaller than a pitch of array of the radiation detecting elements, and adhesion of the first panel and the second panel is maintained,
• wherein the adhesion part includes
• a first portion that is a part of the adhesion part and is located on a side of the first panel in the adhesion part,
• a second portion that is a part of the adhesion part and is located on a side of the second panel in the adhesion part, and
• a third portion that is a part of the adhesion part and is located between the first portion and the second portion,
• and wherein a radiation absorption rate of the third portion is greater than a radiation absorption rate of the first portion and the radiation absorption rate of the third portion is greater than a radiation absorption rate of the second portion.
