An endoscope is configured such that, at a distal end portion of an insertion portion, an objective lens is formed at a position protruded most in a distal end direction, a head top surface of a head top portion of an air/water feeding nozzle is formed at a position protruded in the distal end direction, and then two (first and second) illumination portions 29a, 29b are formed at a position protruded in the distal end direction.
