Abstract
In an X-ray tube apparatus of a rotating anode type, a stator surrounds an anode rotary structure and an insulating container section placed around the outer periphery of a stationary structure such that a portion of its coil conductor located near the anode target side constitutes an expanding flared coil conductor portion. Therefore, it is possible, for the X-ray tube equipped with an envelope having a large-diameter metal section and small-diameter insulating container section, to shorten the axial length from an anode target of the X-ray tube to a far end of the rotary structure and to suppress the build-up of electric charges on the inner surface of the insulating container section.
