The endoscope illuminating optical system includes a light-emitting section and a first optical-path deflecting prism group, which includes a first prism, a second prism, and a third prism. The endoscope objective optical system includes a lens group and a second optical-path deflecting prism group, which includes a fourth prism, a fifth prism, and a sixth prism. A direction of irradiation of illumination light by the endoscope illuminating optical system, and a visual field direction of the endoscope objective optical system, are variable by rotation of the prisms.
