<p>A radiation generating apparatus (1) includes a radiation tube (2) including an electrically insulating tubular member, a cathode (31) provided at one of two openings of the tubular member, and an anode (33) provided at the other opening of the tubular member; an electrically insulating outer tube (5) surrounding at least a peripheral side of the radiation tube with a separation interposed there between; and a container (7) that contains the radiation tube and the outer tube. A space in the container is filled with an insulating liquid (4). At least a portion of a gap (A) between the tubular member and the outer tube is wider than at least one of a gap (C) between the cathode and the outer tube and a gap (B) between the anode and the outer tube.</p> |
