A Raman probe includes: a light source configured to emit light onto an object； a light collector configured to collect Raman-scattered light from the object by reflecting the Raman-scattered light, the light collector including a light incident port, a light emitting port, and a reflective surface including a light incident port portion and a light emitting port portion, a slope of the light incident port portion with respect to an optical axis of the light collector being smaller than a slope of the light emitting port portion with respect to the optical axis； a condenser lens configured to collect the Raman-scattered light collected by the light collector； and a photodetector configured to detect the Raman-scattered light collected by the condenser lens.
