An endoscope includes a side viewing observation section and a forward viewing observation section provided on a distal end side of an insertion portion which is inserted into an observation target for acquiring subject images of an observation target in a circumferential direction and an insertion direction of the insertion portion, respectively, a protruding member that passes within a viewing field of the side viewing observation section and protrudes closer to the distal end side than the side viewing observation section and a shielding section located within a viewing field of the side viewing observation section, which shields light entering the side viewing observation section in a range in which the protruding member passes.
