PROBLEM TO BE SOLVED: To provide a radiation imaging apparatus capable of suppressing deterioration of maintenance property when a plurality of X-ray tubes are provided. A radiation imaging apparatus includes a radiation detector that has an imaging surface that detects radiation that has passed through a subject and that captures a projected image of the subject, and radiation that has a plurality of radiation tubes having different irradiation angles with respect to the imaging surface. And a radiation source configured by a plurality of units that divide and accommodate a plurality of radiation tubes.
