PROBLEM TO BE SOLVED: To provide an X-ray CT apparatus for which the thickness of a slab which can be radiographed by one scanning is large and an X-ray device for such the X-ray CT apparatus. SOLUTION: The X-ray CT apparatus comprises: X-ray generation means (202, 204) for generating two cone beam X-rays to pass through two successive slabs (422, 442) respectively; an X-ray detection means (24) for detecting the two-dimensional intensity distribution of the two cone beam X-rays which have passed through the two slabs respectively; a gathering means for gathering the projection data of a plurality of views of the two slabs on the basis of the detection signals of the X-ray detection means; and a reconstitution means for reconstituting images on the basis of the projection data.
