摘要： In an X-ray tube having an X-ray shielding member (110) allowing an electron ray to pass through an electron passing hole toward a target (108), separately from the cathode-side opening of the electron pass¬ ing hole, a gas exhaust path (112) allowing communication between the inside and outside of the electron passing hole is provided so that gas molecules generated in the electron passing hole can be easily diffused out of the electron passing hole. The degradation of the cath¬ ode caused by accelerated collisions with the cathode, of cations gen¬ erated by collisions of electrons with gas molecules generated in the electron passing hole by a desorption phenomenon due to electron ray irradiation to the target, is reduced.

The distance (L) between the holding member and the end face at the end of the body in the direction in which the electron source / the target face is twice or more as large as the minimum width (i.e. the minimum of LI, L2, L3, L4, L5 or L6) of the channel that is in contact with the outer surface of the X-ray tube at the end face side with respect to the holding member. This allows heat in the target to be quickly radiated, thus allowing X-rays to be generated stably for a long time.

摘要： In a target structure according to the present invention, a target is provided on a central area of an insulating substrate, and a first conductive member for supplying a voltage to the target is provided on a peripheral area of the insulating substrate which is exclusive of an area overlapping the target and is not covered by the target, so that the first conductive member is in contact with and electrically connected to the peripheral portion of the target. Consequently, it is possible to easily form a voltage supply line to the target without preventing diffusion of a heat generated in the target to the substrate and while suppressing emission of an unnecessary X-ray.
