Abstract
The present invention provides a sensor device for detecting a substance contained in a fluid comprising a first photonic crystal region, a second photonic crystal region, a first channel which is connected to the first photonic crystal region, and passes the fluid containing the substance therein, a second channel which is connected to the second photonic crystal region, and passes a fluid for reference therein, an optical waveguide which is connected to the first photonic crystal region and the second photonic crystal region, and guides light, and a detecting section for detecting a difference between a light which has passed through the optical waveguide and the first photonic crystal region and a light which has passed through the optical waveguide and the second photonic crystal region.
