Power supply unit and radiation imaging apparatus including the same

A power supply unit comprising:

• a power supply including a positive terminal portion and a negative terminal portion;
• a substrate connected to each of the positive terminal portion and the negative terminal portion;
• an insulating sheet to which the power supply and the substrate are fixed;
• and
• a sheet fixing member arranged to fix at least one end of a plurality of ends of the insulating sheet.

An apparatus comprising:

• a panel arranged to detect incident radiation;
• a capacitor arranged to supply electric power to the radiation detecting panel;
• a housing arranged to contain the panel and the capacitor;
• and
• a protection member arranged between the capacitor and the housing, and formed by an elastic body.

An apparatus comprising:

• a panel arranged to detect incident radiation;
• a capacitor arranged to supply electric power to the panel;
• and
• a housing arranged to contain the panel and the capacitor,
• wherein the capacitor includes a body portion on which an electrode is laminated, a sealing portion arranged to seal surroundings of the body portion, and a terminal portion arranged to connect the capacitor to an external member,
• a concave portion arranged to concave toward the capacitor is formed in the housing,
• at least a part of the concave portion is formed so as to overlap with the body portion when seen from a direction perpendicular to an incident direction of the radiation, and
• at least a part of one of the sealing portion and the terminal portion is arranged between the concave portion and the panel in the incident direction of the radiation.
