Abstract
An X-ray tube device in one embodiment has an X-ray tube and a container storing the X-ray tube, filled with insulating oil, and having an X-ray emission window. The X-ray tube includes a cylindrical glass envelope holding an anode and a cathode opposite to each other and keeping them in vacuum, and an insulating tube fit over the glass envelope and having an X-ray transmission section. The insulating tube has a base section attached to the container. The base section defines a space communicating between the X-ray transmission section of the insulating tube and the X-ray emission window of the container, and has a container-side end fixed to the container in a liquid-tight manner.
