Abstract:
1. An analysis apparatus comprising: a sensor chip wherein a substrate that has a planar portion, and a diffraction grating that includes a plurality of first protrusions periodically arranged in a period equal to or greater than 100 nm and equal to or less than 1000 nm in a first direction that is parallel to the planar portion, a plurality of base portions that is located between two of the first protrusions adjacent to each other and configures a base of the substrate, a plurality of second protrusions that is formed on upper faces of the plurality of the first protrusions, and a plurality of third protrusions that is formed on the plurality of base portions, has a surface formed from a metal, and is formed on the planar portion; and a light source that emits light to the sensor chip wherein a wavelength of the light is longer than the period of the second protrusions and the third protrusions; and a photo detector that detects light acquired by the sensor chip.
