A biochip to be used for infrared reflection absorption spectroscopy analysis, which is obtainable by forming a metallic layer and an active layer made from a nonmetallic material and has a film thickness less than an infrared wavelength and remarkably flat surface on a solid base and immobilizing a probe on the active layer. A biochip analysis apparatus including the biochip, a liquid passing unit for supplying a sample liquid containing a test substance to the biochip, and an optical system entering infrared light to the biochip and detecting a reflected infrared light. A biochip analysis method using the apparatus. n As described above, the novel biochip that is useful for infrared reflection absorption spectroscopy analysis, the biochip analysis apparatus incorporating the biochip, and the biochip analysis method are provided. |
