PROBLEM TO BE SOLVED: To improve resistance to an unnecessary electromagnetic wave that affects internal electric components, to obtain a stable image without any artifacts, at the same time, to stabilize the characteristics of the electric components by securing a radiation path from the electric components for preventing temperature rising, and to obtain a high SN ratio. SOLUTION: The X-ray equipment has a solid photodetector 37, a signal- processing section 39 for allowing the solid photodetector 37 to be subjected to signal processing or for driving the solid photodetector 37, a power supply section, a retention plate 34 that fixes the solid photodetector 37 so that the signal-processing section 39 is at an X-ray incidence side and a power supply section is opposite to the solid photodetector 37, a conductive case 31 for enclosing the photodetector 37, signal-processing section 39, power section, and retention plate 34 inside, a fixing section for fixing the retention plate 34 to the inside of the case 31, and a heat radiation section 45 that transmits heat generated by the signal-processing section 39 that is fixed to the retention plate 34 and an electrical heating element inside the power supply section to the case 31 while being insulated.
