This X-ray generator comprises: an X-ray tube; an X-ray tube housing; and a power supply unit which comprises an internal substrate for supplying voltage to the X-ray tube, sealed in an insulating block. A first space is defined by the upper surface of the insulating block and the inner surface of the X-ray tube housing. A second space is defined by an outwardly-opening recess formed on a lateral surface of the insulating block and a sealing material for sealing the opening of the recess. A communication hole by which the first space and the second space are in communication with each other is provided in the insulating block.
