To prove an optical probe that can illuminate an entire desired region at one time, even in a narrow space. An optical probe including: a linear light guide to guide light from a light source device; a planar emitter to be connected to a tip portion of the linear light guide, to emit the light; a reflective surface provided in a part of the planar emitter, to reflect the light having entered the planar emitter; and an emitting surface provided so as to face the reflective surface, to allow the light reflected by the reflective surface to be emitted from a region of the reflective surface. |
