PROBLEM TO BE SOLVED: To provide a rotating anode X-ray tube excellent in G-tolerance, outputting a high power, and having a high reliability. SOLUTION: The rotating anode X-ray tube is provided with: a fixed shaft 13 having a first large diameter part 26-1 at a part and with a flow channel 30 for cooling fluid to flow along formed inside; a cooling tub 31 made by enlarging a flow channel diameter of a part of the flow channel 30 by thinly forming a thickness of the first large diameter part 26-1 of the fixed shaft 13; a rotating cylinder 19 supported to the fixed shaft 13 in free rotation by covering an area including the first large diameter part 26-1 out of the fixed shaft 13 through liquid metal 23; a hollow disc-shaped target 15 fitted to an outer periphery face of the rotating cylinder 19, a cathode 16 arranged in opposition to the target 15; and a vacuum envelope 18 housing the fixed shaft 13, the rotating cylinder 19, the target 15 and the cathode inside, for supporting the fixed shaft 13.
