PROBLEM TO BE SOLVED: To provide an X-ray generating device that can realize heat reduction from the shaft by a temperature gradient device. SOLUTION: This is a heat energy transmission device that is used together with an X-ray generating device, that is, an X-ray system which contains an anode assembly 40 having a target 48, a cathode assembly that is arranged at a distance from the anode assembly 40 and constructed to emit electrons for colliding with the target and generates X rays and the remaining heat energy, and a rotating shaft 58 that is supported by a bearing assembly 50. The heat energy transmission device comprises a temperature gradient device 72 that is arranged in the vicinity of one end of the shaft 58 and, by transmitting heat, is capable of operating of removing heat from that end of the shaft 58, and a fin structure 80 that is arranged at the vicinity of the temperature gradient device 72 and, by transmitting heat, is capable of operating of convection-cooling the temperature gradient device 72.
