Radiation imaging apparatus and radiation imaging system

Abstract

A radiation imaging apparatus includes: a radiation detection panel; an electrical component electrically connected to the radiation detection panel; and a housing for housing the radiation detection panel including a top configured to cause the radiation to enter the housing and impinge on the radiation detection panel, and a bottom arranged on a side opposite to the top. An inner surface of the bottom on a side of the radiation detection panel includes a supporting surface configured to support the radiation detection panel. A concave portion defined by a part of an outer surface of the bottom is formed on a side of the bottom opposite to the side of the radiation detection panel i.e. on the outside of the housing. The electrical component is arranged in the concave portion.
