Disclosed is a photography tool which can use various image capturing CCD sensors having different external shapes, facilitates creation of an image exhibiting excellent reproducibility by positioning various sensors accurately, suppresses strangeness by stabilizing the occlusion state in the oral cavity, and ensures good holding state. In a photography tool (1) with an exclusive sensor holder for mounting a CCD sensor for capturing a dental X-ray image, a sensor mounting portion corresponding to the external shape of a sensor (16) is formed by inclining the sensor supporting substrate (18) of a sensor holder (17) at a predetermined angle and projecting curved portions (19, 20) from the upper and lower ends of the supporting substrate (18), a fitting protrusion (25) is provided on the supporting substrate (18), a fitting groove (12) to which the fitting protrusion (25) is fitted and which has the identical cross-sectional shape is provided in the main block (9) for occlusion, the shape of the sensor mounting portion is changed every time when the external shape of the sensor (16) is different, various holders (17) are made by changing the vertical position of the sensor mounting portion every time when the image capturing position for a tooth (28) to be inspected is different, and each holder (17) is provided with the fitting protrusion (25) of the identical shape.
