Abstract: Fifteen radiation tubes are arranged in a radiation source of the mammography apparatus. An irradiation field limiter includes a plate-like member having a plurality of through holes that function as irradiation openings. Adjacent through holes are arranged at an interval of one radiation tube.

Therefore, one through hole is shared by two radiation tubes.
