ABSTRACT:
A supporting member supports an anode target at one end thereof and is provided with an attachment portion around the outer circumference of the other end. The attachment portion is attached to the inner circumferential surface of the cylindrical portion of the second vacuum envelope member so that the heat conductivity from the supporting member to the second vacuum envelope member can be improved by means of the attachment portion. A terminal is provided at the end surface portion on the side of the other end of the second vacuum envelope member for applying a voltage to the anode target. The terminal is positioned away from the attachment portion so that the temperature of the insulating material that insulates the terminal can be kept low and the insulating characteristics can be ensured over the long term.
