A sensor for detecting a target of interest is provided. A sensor 100a includes a container 101, a probe 113 disposed in the container for binding to a target 901 of interest, a circulating member 220 for circulating the substance in the container, a light source, A light receiver, a light selection unit for causing the light receiver to receive light of a predetermined wavelength, and a detection device for generating an electrical signal may be included. The magnitude of the electrical signal reflects the amount of light received by the receiver. The container is located between the light source and the light receiver. In addition, this container is comprised so that the course of the light inject | emitted from this probe and this light source may be located in a different area | region within this container.
