PROBLEM TO BE SOLVED: To provide a fluoroscopic apparatus capable of preventing the brightness of a fluoroscopic image from being changed when changing a fluoroscopic magnification, and preventing the visual field of an X-ray detector from being changed or preventing the X-ray intensity transmitting a fluoroscopic object from being changed, when changing the fluoroscopic direction. SOLUTION: An X-ray generation device 1 and the X-ray detector 2 are supported by a common support member 4 in the opposite state. The support member 4 is supported by a base member 6 movably in the direction crossing a horizontal sample table 3, and simultaneously supported movably around a horizontal axis 5a passing near the surface of the sample table 3. Hereby, the X-ray generation device 1 and the X-ray detector 2 are enabled in the state keeping the fixed position relation to change the positions thereof in the X-ray optical axis direction to the sample table 3, and also enabled in the mutually facing state to be tilted relative to the sample table 3.
