A radiation generating apparatus (20) includes a cathode array (12) including a plurality of electron emitting portions (11), and an anode array (10) including a plurality of targets (15) and a chained connection unit (1) that connects the targets (15), the targets (15) being arranged at locations corresponding to locations of the respective electron emitting portions (11). The chained connection unit (1) includes a plurality of shielding members (2) and a thermal transfer member (3), the shielding members (2) being arranged at locations corresponding to the locations of the respective targets (15), and the thermal transfer member (3) having a thermal conductivity higher than a thermal conductivity of the shielding members (2). The thermal transfer member (3) has a portion that is continuous in a direction in which the targets (15) are arranged.
