ABSTRACT:
An optical element of the present invention includes a conductive microstructure having a conductive property, and detects an optical spectrum signal varied by the binding of measured molecules on the surface of the conductive microstructure. The optical element has a distribution in the binding capacity of the measured molecules on the surface of the conductive microstructure in the direction of the electric displacement vector generated inside the conductive microstructure. As a result, it is possible to provide an optical element capable of measuring the density at high accuracy without depending on the binding position of the measured molecules.
