An X-ray tube 1 in which a cathode 73 is heated to emit electrons 80, and the electrons 80 are bombarded against an anode target 32, thereby generating X-rays 81, includes a stem substrate 4 mounted on an opening 22 of a container 21 housing the cathode 73, a plurality of pins 5 extending through the insulating substrate 4 and adapted to supply a voltage into the container 21, and pin covers 6 mounted on the pins 5 in the container 21 and arranged at positions away from a surface of the stem substrate 4 to cover base portions of the pins 5. <IMAGE> |
