PROBLEM TO BE SOLVED: To provide a CT device capable of blocking and absorbing noises radiated from a source of noises within a frame or noises impinging thereon from the outside and thus reducing the influence of the noises by forming noise- absorbing conductive layers on frame covers and to provide a method for forming the shield structure of the CT device. SOLUTION: This CT device has a frame 10 provided at its center part with an imaging opening 5 for exposing to X-rays a patient placed on a bed and inserted therein from the direction indicated by the arrow A. When the side of the frame 10 from which the patient is inserted is the front, frame covers 10a, 10b, 10c, 10d, 10e are mounted respectively on the front face, upper face, side faces, and rear face of the frame 10. Noise absorption type conductive layers which absorb noises are formed inside the frame covers 10a, 10b, 10c, 10d, 10e, 10f.
