Abstract
A purpose of the present invention is to provide a sensor with high sensitivity or high target substance selectivity. A sensor that includes a structure having an internal space into which a detection target is capable of flowing, a light-emitting element, and a photo-receptor element is provided. The sensor is disposed so that light emitted from the light-emitting element passes through the internal space to reach the photo-receptor element. A wavelength of the light emitted from the light-emitting element falls within a range from 2.5 μm to 15 μm inclusive. A length of the internal space in a direction perpendicular to an extension direction of the structure should preferably be less than or equal to 1000 μm.
