PROBLEM TO BE SOLVED: To increase convenience relating to an intraoral camera. SOLUTION: The intraoral camera includes: a body case 1; an imaging window 3a; an illuminating element 9; a diaphragm driving unit 14; a focal lens 11 optically connected to the diaphragm driving unit 14; an imaging unit 10 optically connected to a back side of the focal lens 11; and a controller 19 for receiving image data of the imaging unit 10. The focal lens 11 includes an autofocus driving unit 12. The controller 19 includes a contrast determination unit 20 and an imaged part determining unit 21. The contrast determination unit 20 determines that the image data have low contrast. When the imaged part determining unit 21 determines that an imaging unit of the image data is in the oral cavity, the autofocus driving unit 12 moves a focus position of the focal lens 11 to a proximate imaging position.
