Abstract: A fundus observation apparatus includes an optical system, two concave mirrors, and a holding member. The optical system is configured to project light from a light source onto a fundus of an eye to be examined, and to receive returning light from the fundus. The two concave mirrors have concave reflective surfaces, respectively, configured to guide the light from the optical system to the fundus, and to guide the returning light to the optical system. The holding member is configured to be capable of holding the two concave mirrors in a state where the concave mirrors are arranged on both sides of the holding member so that the concave mirrors are positioned in a default relative position in a predetermined one-dimensional direction or predetermined two-dimensional directions.
