Abstract

A radiation imaging apparatus includes a radiation detector and a housing that accommodates the detector. The housing has an entrance surface on which radiation is incident, a rear surface opposite the entrance surface, and a plurality of side surfaces connecting them. At least one side surface includes a fastening portion at which a plurality of members constituting the housing are connected and, on the at least one side surface, (a) a first inner-wall portion located on an entrance-surface side and closer to an outermost surface of the at least one side surface, and (b) a second inner-wall portion located on a rear-surface side of the first inner-wall portion and including the fastening portion, are provided. An end portion of the radiation detector on the at least one side-surface side is disposed opposite the first inner-wall portion and is closer to the outermost surface than the second inner-wall portion.
