PURPOSE: A photo biosensor and a method for manufacturing the same are provided to improve sensitivity through thickness change of dielectric layer and to be easily applied in an optical device. CONSTITUTION: A biosensor comprises a light source part, a biosensor, a light detection part. The light source generated from the light source part includes a tungsten lamp, tungsten halogen lamp, xenon lamp, and laser. The biosensor also comprises a prism, metal thin film layer, and a dielectric layer. The light detection part measures minute refraction rate change. A plurality of nanoprotrusions(135) are formed on the surface of the metal thin film layer contacting the dielectric layer.
