An endoscope includes: a first objective lens that causes an image of a first object to be observed to be formed; a second objective lens that causes an image of a second object to be observed to be formed; a light guide that guides illuminating light from a light source to an insertion portion; a light distribution member that distributes light from the light guide between a first observation direction and a second observation direction; a light amount varying portion for changing light amount proportions with respect to light emitted in the first observation direction and light emitted in the second observation direction; a distance detection portion that measures a second distance between the second objective lens and an object to be observed in the second observation direction; and a control portion that controls the light amount varying portion based on a second distance signal.
