PROBLEM TO BE SOLVED: To provide a quantitative staining evaluation method of high reproducibility applicable for various members, and capable of detecting a subtle difference in stain, a staining evaluation device therefor, and a method of manufacturing an optical member. SOLUTION: The problem to be solved is solved by the staining evaluation method of the present invention for evaluating a degree of the stain on a surface of a testing object 3 contacting with an optical waveguide substrate 1, by making light 2 get incident into one end side of the optical waveguide substrate 1 and by detecting the light 2 emitted from the other end side, under the condition where the testing object 3 is brought into close contact with one face out of a pair of cut faces opposed in parallel each other of the optical waveguide substrate 1 in a slab type optical waveguide. The problem to be solved is solved by the staining evaluation device of the present invention having the optical waveguide substrate 1 installed to contact closely with the testing object 3, a light source for making the light 2 get incident into the one end side of the optical waveguide substrate 1, and a detector for detecting the light 2 emitted from the other end side of the optical waveguide substrate 1.
