1. An X-ray CT apparatus comprising:

  • an X-ray source which emits X-rays to an object;

    an X-ray detector which is disposed opposite the X-ray source in order to detect X-rays transmitted through the object;

    a rotary disk in which the X-ray source and the X-ray detector are mounted and which rotates around the object;

    an image reconstruction device which reconstructs a tomographic image of the object on the basis of the amount of transmitted X-rays detected by the X-ray detector; and

    an image display device which displays the tomographic image reconstructed by the image reconstruction device,wherein the X-ray detector has a collimator plate, and a scintillator array, a photoelectric conversion element array and a substrate that are bonded in order from an X-ray incidence direction, andthe collimator plate is disposed such that one of a pair of opposite sides of the collimator plate is bonded to a lower support plate bonded on the scintillator array and the other side is bonded to an upper support plate and directions of the opposite sides are the same as a rotation axis direction of the X-ray CT apparatus.
