PROBLEM TO BE SOLVED: To provide an X-ray tube device with a compact size and large capacity, capable of displacing a focusing point in the tube container. SOLUTION: The device includes a support structure 16 having a support by an X-ray tube support 12 inside the tube container 14 at a colliding position of electrons on a target 6 surface in an anode direction 2, and having a support in a range up to an end part of an outer surrounding apparatus 3 of an opposite direction to a connection position of the anode 2 and the outer surrounding apparatus 3 based on the above position, and to be offset by displacement of the anode 2 due to heat at the time of X-ray generation by expansion of the outer surrounding apparatus 3.
