摘要：
A highly sensitive and reliable optical sensor which has a low production cost, and facilitates a detection is provided. An optical sensor 1 that detects a predetermined detection target includes a concavo-convex structure 2 which has a predetermined form periodically arranged in a two-dimensional manner and which functions as a photonic crystal, a metal layer 3 which is formed on a surface of the concavo-convex structure 2 and which is capable of exciting localized surface plasmon resonance, and an adsorption element which is formed on the surface of the metal layer 3 and adsorbs the detection target. The detection target is detected based on optical characteristics before and after the detection target is adsorbed on the optical sensor 1.
