There is provided an intraoral teeth image taking apparatus capable of simultaneously taking from a plurality of directions a group of high-precision images for calculation of high-precision three-dimensional data required, for example, when artificial teeth are made. The intraoral teeth image taking apparatus includes an image taking tray part 101 having a plurality of image taking devices 121 capable of simultaneously taking a plurality of images of a row of teeth in an oral cavity from a plurality of directions, and a plurality of projection devices 151 capable of projecting a plurality of patterns. The image taking tray part is formed in a U-shape in conformity with the shape of the row of teeth and the cross-sectional shape of the tray is concave such as to be capable of being put on a distal end portion of the row of teeth.
