<p>The invention relates to an X-ray generating device. A cylindrical body (25) includes a flange portion (26), an opening end portion (27) protruding from the front side of the flange portion (26), and a maintenance target (31). The opening end portion (27) is disposed in a through hole (4a) of a front panel (4) of the X-ray generating device. The target (31) is disposed near the outer surface of the front panel (4). The front panel (4) and the cylindrical body (25) have a property of heat conduction. The flange portion (26) of the cylindrical body (25) contacts with the front panel (4) of the X-ray generating device. Heat generated in the target (31) can be released to the front panel (4) through the flange portion (26).</p> |
