An oral observation device (1) comprises: a body (2) that includes a gripping part (21), an arm part (22) that extends from the tip end of the gripping part (21) along the longitudinal direction of the gripping part (21), a camera module storage part (23) formed at the tip end of the arm part (22), and a light-emitting element storage part (24) formed at the arm part (22); a camera module (3) provided inside the camera module storage part (23); and a light-emitting element (4) provided inside the light-emitting element storage part (24). The light-emitting element (4) is provided inside the light-emitting element storage part (24) in a state where the light-emitting element (4) is inclined relative to the longitudinal direction of the gripping part (21) such that the light-emitting element (4) uniformly illuminates the imaging range of the camera module (3).
