An X-ray device for irradiating a beam of X-rays on an object to capture an X-ray image of the object is smaller in size and weight than conventional ones. The X-ray device includes an X-ray tube for generating the beam of X-rays and irradiating the beam of X-rays on the object, a shutter arranged around an X-ray irradiation axis for regulating an X-ray irradiation region on which the beam of X-rays is irradiated through the object, and a visual indicator unit arranged on the shutter for movement together with the shutter, the visual indicator unit being designed to visually indicate the X-ray irradiation region. In the X-ray device, the X-ray irradiation region is visually indicated by laser light without having to use a lamp otherwise provided between the X-ray tube and the shutter.
