PROBLEM TO BE SOLVED: To provide an optical biosensor capable of measuring the change quantity of evernescent waves with high precision. SOLUTION: This optical biosensor includes a total reflection layer 10 for permitting incident light to transmit while totally reflecting the same, the incident side grating 11a and the emitting side grating 11b brought into contact with the total reflection layer 10 in a mutually spaced-apart state and the sensing film 12 brought into contact with the total reflection layer 10 to contain the enzyme and color forming reagent provided between the incident side grating 11a and the emitting side grating 11b.
