An X-ray object positioning apparatus for use in X-ray imaging apparatus which irradiates X-rays an object to be examined to produce an X-ray absorption coefficient of a desired region of the object by means of X-rays transmitted through the object. The X-ray object positioning apparatus comprises an object fixing means for fixing and holding the object; an imaging position moving means for relatively moving an X-ray imaging target area relative to the fixed object on the object fixing means; and display means for variably showing the relative positional relation between an object model corresponding to the object and an imaging target area index corresponding to the X-ray imaging target area. The position between the object and the imaging target area is set by the moving operation for the position between the object model and the imaging target area index on the display means, in a manner that the relative positional relation between the object model and the X-ray imaging target area index, both displayed on the display means, conforms with the relative positional relation between the object and the X-ray imaging target area, moved by the imaging position moving means.
