In both of normal observation and close observation, sufficient light distribution is ensured and favorable observation is thereby performed. Provided is an endoscope including an observation optical system 1 that allows a magnified observation close to a subject, and a plurality of illumination optical systems 2 that illuminate the subject with illuminating light, wherein in a close observation in which a distance between a distal end face of an insertion portion and the subject is 1.5 mm to 2.5 mm, where I TM is a maximum brightness within an observation view field angle and I TC is a center brightness, and in a normal observation in which the distance between the distal end face of the insertion portion and the subject is 50 mm, where I CW is a center brightness and I WS is a brightness at a position of 80% of a maximum view angle, the following conditional expressions are satisfied: 0.3 < I TC / I TM < 0.45 0.15 < I WS / I WC < 0.25 and 0.3 < f L f T / Õ L I H < 0.6 where f L is a focal length of each of the entire illumination optical systems, f T is a focal length of the entire observation optical system in a maximum magnification, Õ L is an outer diameter of a lens that is farthest on an object side of each illumination optical system, and I H is a maximum image height of the observation optical system.
