PROBLEM TO BE SOLVED: To provide an imaging device for supporting observation of an oral cavity, which can easily capture both intraoral imaging and extraoral imaging. An imaging device (10) for supporting observation of an oral cavity is provided with a main body (20) and at least one front surface of the main body (20) provided on the optical axis of the lens and convex toward the rear as a whole. An oral cavity imaging appendage 30 having a mirror 31 and at least one light source 211a, 212a, 215a provided on the front surface of the main body 20 or on the outer periphery of the mirror 31 are provided. Only the appendix 30 is inserted into the oral cavity at the time of imaging the oral cavity.
