Abstract:
     An X-ray apparatus includes a rotation-anode type X-ray tube 11 which is configured such that a rotatable anode target 15 and a cathode 16 that is disposed to be opposed to the anode target 15 are accommodated within a vacuum envelope 13, a stator 26 which generates an induction electromagnetic field for rotating the anode target 15, a housing 10 which accommodates and holds at least the rotation-anode type X-ray tube 11, a circulation path which is provided near at least a part of the rotation-anode type X-ray tube 11, and through which a water-based coolant is circulated, and a cooling unit 27 including a circulation pump 27a, which is provided at a position along the circulation path and forcibly feeds the water-based coolant, and a radiator 27b which radiates heat of the water-based coolant, wherein an amount of dissolved oxygen at 25 DEG C in the water-based coolant is 5 mg/liter or less.
