Abstract: The present invention provides a sensor cell that has excellent measurement accuracy in repetitive measurement. An optical waveguide of the present invention includes a cladding layer and a core layer buried in the cladding layer so that at least one surface of the core layer is exposed. A water contact angle of a surface of the cladding layer on which the core layer is exposed is 80° or more. An SPR sensor cell and a colorimetric sensor cell of the present invention each include the optical waveguide of the present invention.
