Abstract
An intraoral camera including a main body case, an intraoral insertion component mounted on the front side of the main body case, an imaging window provided to the intraoral insertion component, and an imaging device that is optically linked to the imaging window and is disposed inside the main body case or inside the intraoral insertion component. Illumination elements are disposed at portions of an outer peripheral wall face that are substantially opposite each other in the horizontal direction. These illumination elements are inclined toward the outside of the imaging window in the center of the imaging window, and the outer peripheral wall face that is substantially opposite these illumination elements in the vertical direction is constituted as a light collecting face that is inclined toward the outside of the imaging window in the center of the imaging window.
