An optical waveguide sensor for glucose measurement comprises a substrate, a first optical waveguide layer formed on a surface of the substrate, an entrance grating and an exit grating which are formed contacting with the first optical waveguide layer and being spaced from each other, a second optical waveguide layer located between the entrance grating and the exit grating while being in contact with the first optical waveguide layer, the second optical waveguide layer having a higher refractive index than that of the first optical waveguide layer, and a functioning layer containing an enzyme and a coloring reagent which is formed on the second optical waveguide layer.
