PROBLEM TO BE SOLVED: To improve excitation efficiency, light-collecting efficiency, surface fixed capability of a protein and analysis accuracy of measurement in an optical probe for measuring, based on an optical technique. SOLUTION: The optical probe 1 comprises an optically transparent synthetic resin, and is provided with a cylindrical optical waveguide 2 and a light-entering/exiting part 3 disposed in an upper part, having a convex lens profile and entering and exiting a light. A flange 4 is provided between the optical waveguide 2 and the light entering/exiting/ part 3 and is used for mounting the optical probe 1 to a measuring apparatus. The optical probe 1 has a controlled surface roughness at a particular region on a surface of the optical waveguide 2, and the surface roughness is made small at the light-entering/exiting sides, and is made large at the tip.
