A measurement probe includes: a plurality of optical fibers including an illumination fiber configured to propagate light to irradiate a measuring object and including a light receiving fiber configured to receive scattered light returned from the measuring object; and an optical member. The optical member is provided on an end portion of the measurement probe so as to face the measuring object, abuts on the plurality of optical fibers, and includes an exposed portion in which a part of a side portion of the optical member is exposed on an outside of the measurement probe, the side portion forming a surface of the optical member along a longitudinal direction of the measurement probe, the exposed portion being provided on an end portion of the optical member opposite to where the optical member abuts on the plurality of optical fibers.
