The purpose of the present invention is to provide a jig for position correction, capable of quickly and precisely adjusting a radial center of an X-ray radiator and an optical axis of an X-ray camera. The jig for position correction of an X-ray position measurement device is used to adjust an optical axis of the X-ray camera and a radial center of the X-ray radiator. The X-ray position measurement device measures a subject by photographing an image, based on the X-ray radiated from the X-ray radiator, through the X-ray camera. The present invention comprises: a first penetration part penetrating the X-ray radiated from the X-ray radiator; and a second penetration part penetrating the X-ray, penetrated by the first penetration part, and then projecting the X-ray to the X-ray camera. The present invention projects a first projection image, based on the X-ray penetrated by the first penetration part; and a second projection image, based on the X-ray penetrated by the second penetration part, to the X-ray camera.
